The initial public offering of Units in each Trust has been completed. The Units
offered hereby are issued and outstanding Units which have been acquired by the
Sponsor either by purchase from the Trustee of Units tendered for redemption or
in the secondary market.
 
The objectives of each Trust are the providing of interest income which, in the
opinion of counsel is, under existing law, excludable from gross income for
Federal income tax purposes (except in certain instances depending on the Unit
Holder), through investment in a fixed portfolio consisting primarily of
long-term state, municipal and public authority debt obligations, and the
conservation of capital. In addition, in the opinion of bond counsel to the
issuers of the obligations, the interest income on the obligations held by the
underlying unit investment trusts composing Multistate Series 52 designated as
the California Trust (Insured) and the New York Trust (Insured) (the 'California
Trust (Insured)' and the 'New York Trust (Insured),' collectively the 'State
Trusts,' or singularly, the 'State Trust') (the 'Trusts' or the 'Trust' or in
the case of the California Trust (Insured) and the New York Trust (Insured) the
'Insured Trusts' or the 'Insured Trust' as the context requires), is exempt from
state and any local income taxes to individual Unit Holders resident in the
State for which the State Trust is named. There is, of course, no guarantee that
the Trusts' objectives will be achieved. The value of the Units of each Trust
will fluctuate with the value of the portfolio of underlying Securities. Each
municipal bond in an Insured Trust is covered by an irrevocable insurance policy
as a result of which the Units of each Insured Trust were rated 'AAA' by
Standard & Poor's Corporation as of the Date of Deposit. Insurance guaranteeing
the scheduled payment of principal of and interest on the securities in the
California Trust (Insured) and the New York Trust (Insured) to the maturity of
such Securities has been obtained at the cost of the issuer at the time of
issuance. No representation is made as to the insurers' ability to meet their
commitments. The Securities in Series 150 are not insured. The Securities in the
Trusts are not insured by The Prudential Insurance Company of America. The
Prospectus indicates the extent to which interest income of each Trust is
subject to alternative minimum tax under the Internal Revenue Code of 1986, as
amended. See 'Schedule of Portfolio Securities' and 'Portfolio Summary.'
 
                            Minimum Purchase: 1 Unit
 
PUBLIC OFFERING PRICE of the Units of each Trust is equal to the aggregate bid
side evaluation of the underlying Securities in each Trust's Portfolio divided
by the number of Units outstanding in such Trust, plus a sales charge as set
forth in the table herein. (See Part B--'Public Offering of Units--Volume
Discount.') Units are offered at the Public Offering Price plus accrued
interest. (See Part B--'Public Offering of Units.')

                                    SUMMARY
 
    National Municipal Trust, Series 150 ('National Trust (Uninsured)') and
Multistate Series 52 which consists of two separate underlying unit investment
trusts designated as the California Trust (Insured) and the New York Trust
(Insured) (the 'California Trust (Insured)' and the 'New York Trust (Insured),'
collectively, the 'State Trusts,' or singularly, the 'State Trust') (the
'Trusts' or the 'Trust' or in the case of the California Trust (Insured) and the
New York Trust (Insured) the 'Insured Trusts' or the 'Insured Trust' as the
context requires) are composed of interest-bearing municipal bonds (the
'Securities.') The Securities in the State Trusts are issued primarily by or on
behalf of the State for which the State Trust is named and counties,
municipalities, authorities and political subdivisions thereof. The interest on
these bonds, in the opinion of bond counsel to the issuing governmental
authorities is, under existing law, excludable from gross income for Federal
income tax purposes (except in certain instances depending on the Unit Holder)
and, as respects the underlying State Trusts, exempt from State and any local
income taxes to individual Unit Holders resident in the State for which the
State Trust is named.
 
    INSURANCE guaranteeing the scheduled payments of principal of and interest
on the Securities in the portfolios of the Insured Trusts has been obtained by
the issuer at the cost of the issuer at the time of issuance of the Securities
from AMBAC Indemnity Corporation ('AMBAC'), Capital Guaranty Insurance Company
('Cap. Gty.'), Financial Security Assurance ('FSA'), Municipal Bond Insurance
Association ('MBIA'), Municipal Bond Investors Assurance Corporation ('MBIAC'),
and/or Financial Guaranty Insurance Company ('Financial Guaranty' or 'FGIC')
(singularly, each an 'Insurance Company' and, collectively, the 'Insurance
Companies.') (See Part B--'The Trust--Insurance on the Securities in the
Portfolio of an Insured Trust.') As a result of the insurance, the Securities
and the Units of each Insured Trust have received a rating of 'AAA' by Standard
& Poor's Corporation. There can be no assurance that Units of the Insured Trusts
will retain this 'AAA' rating. There is, of course, no guarantee that the
objectives of the Insured Trusts will be achieved since an issuer may be unable
to meet its principal and interest payment obligations and, in such event, the
Insurance Company involved may be unable to satisfy its insurance obligation.
Insurance is not a substitute for the basic credit of an issuer, but supplements
the issuer's existing credit and provides additional security therefor. NO
REPRESENTATION IS MADE AS TO THE ABILITY OF THE INSURANCE COMPANIES TO MEET
THEIR COMMITMENTS.
 
    MONTHLY DISTRIBUTIONS of principal, premium, if any, and interest received
by each Trust will be made on or shortly after the twenty-fifth day of each
month to Unit Holders of record as of the immediately preceding Record Date.
(See Part B--'Rights of Unit Holders--Distribution of Interest and Principal.')
Alternatively, Unit Holders may elect to have their distributions reinvested in
the Reinvestment Program of the Sponsor, as, if and when such program is
available to Unit Holders. (See Part B--'Reinvestment Program.')
 
    THE SPONSOR, although not obligated to do so, presently intends to maintain
a secondary market for the Units in each Trust based on the aggregate bid side
evaluation of the underlying Securities, as more fully described under Part
B--'Public Offering of Units--Secondary Market--Public Offering Price.' If such
a market is not maintained, a Unit Holder may be able to dispose of his Units
only through redemption at prices based on the aggregate bid side evaluation of
the underlying Securities. (See Part B--'Rights of Unit
Holders--Redemption--Computation of Redemption Price per Unit.')
 
    SPECIAL CONSIDERATIONS. An investment in Units of each Trust should be made
with an understanding of the risks which an investment in fixed rate long-term
debt obligations may entail, including the risk that the value of the Units will
decline with increases in interest rates. Insurance obtained by the Security
issuer does not guarantee the market value of the Securities or the value of the
Units. Any such insurance obtained by the issuer may be considered to represent
an
                                      A-i
 
<PAGE>
element of market value in regard to the Securities thus insured. The insurance
on the Securities in the Insured Trusts does not protect Unit Holders from the
risk that the value of the units may decline. (See Part B--'The Trust--Portfolio
Summary.') The ratings of the Securities set forth in Part A--'Schedule of
Portfolio Securities' may have declined due to, among other factors (including a
decline in the creditworthiness of an insurer in the case of an insured trust
which may also result in a decline in the 'AAA' rating of the Units of an
insured trust), a decline in creditworthiness of the issuer of said Securities.
 
    Note: In Part B 'Rights of Unit Holders--Distribution of Interest and
Principal,' The Minimum Principal Distribution Amount is amended to read $1.00
per Unit.
 
    Note: The second paragraph in Part B 'Sponsor' is amended to delete such
paragraph and replace it with the following:

Portfolio Summary
 
   National Trust (Uninsured)
 
    The Portfolio contains 10 issues of Securities of issuers located in 8
states. One of the issues (3.0% of the Trust) is a general obligation of a
governmental entity and is backed by the general taxing powers of that entity.
The remaining issues are payable from the income of specific projects or
authorities and are not supported by the issuer's power to levy taxes. Although
income to pay such Securities may be derived from more than one source, the
primary sources of such income and the percentage of issues deriving income from
such sources are as follows: convention center facilities: 15.1%* of the Trust;
health and hospital facilities: 40.4%* of the Trust; housing facilities: 11.8%*
of the Trust; industrial revenue facilities: 19.9%* of the Trust; water and
sewer facilities: 9.8%* of the Trust. The Trust is concentrated in health and
hospital facilities Securities.
 
    The Portfolio also contains Securities representing 7.5%* of the Trust
(single-family housing securities) which are subject to the requirements of
Section 103A of the Internal Revenue Code of 1954, as amended, or Section 143 of
the Internal Revenue Code of 1986.
 
    Approximately 7.5%* of the Securities in the Trust also contain provisions
which require the issuer to redeem such obligations at par from unused proceeds
of the issue within a stated period which typically does not exceed three years
from the date of issuance of such Securities.
 
    51.7%* of the Securities in the Trust are rated by Standard & Poor's
Corporation (32.2%* being rated AAA and 19.5%* being rated A) and 48.3%* of the
Securities in the Trust are rated by Moody's Investors Service (7.5%* being
rated Aa, 27.0%* being rated A and 13.8%* being rated Baa). For a description of
the meaning of the applicable rating symbols as published by Standard & Poor's
and Moody's, see Part B--'Bond Ratings.' It should be emphasized, however, that
the ratings of Standard & Poor's and Moody's represent their opinions as to the
quality of the Securities which they undertake to rate and that these ratings
are general and are not absolute standards of quality.
 
    Five Securities in the Trust have been issued with an 'original issue
discount.' (See Part B--'Tax Status.')
- ------------
    * Percentages computed on the basis of the aggregate bid price of the
Securities in the Trust on August 21, 1997.
 
                                      A-ii
 
<PAGE>
    Of these original issue discount bonds, approximately 9.2% of the aggregate
principal amount of the Securities in the Trust (although only 3.0%* of the
aggregate bid price of all Securities in the Trust) are zero coupon bonds
(including bonds known as multiplier bonds, money multiplier bonds, capital
appreciation bonds, capital accumulator bonds, compound interest bonds, and
discount maturity payment bonds).
 
   Alternative Minimum Tax
 
    As of the date of the Summary of Essential Information, the Sponsor's
affiliate, The Prudential Investment Corporation, estimates that 25.7% of the
estimated annual income per Unit consists of interest on private activity bonds,
which interest is to be treated as a tax preference item for alternative minimum
tax purposes (See 'Tax Status' and 'Schedule of Portfolio Securities.')
 
   California Trust (Insured)
 
    The Portfolio contains 6 issues of Securities of issuers located in the
State of California. All of the issues are payable from the income of specific
projects or authorities and are not supported by the issuer's power to levy
taxes. Although income to pay such Securities may be derived from more than one
source, the primary sources of such income and the percentage of issues deriving
income from such sources are as follows: health and hospital facilities: 17.0%*
of the Trust; port facilities: 29.1%* of the Trust; governmental lease payments:
18.6%* of the Trust; special tax bonds: 35.3%* of the Trust. The Trust is
concentrated in ports facilities and special tax bonds.
 
    100% of the Securities in the Trust are rated AAA by Standard & Poor's
Corporation. For a description of the meaning of the applicable rating symbols
as published by Standard & Poor's see Part B--'Bond Ratings.' It should be
emphasized, however, that the ratings of Standard & Poor's represent its opinion
as to the quality of the Securities which it undertakes to rate and that these
ratings are general and are not absolute standards of quality.
 
    Three Securities in the Trust have been issued with an 'original issue
discount.' (See Part B--'Tax Status.')
 
    Of these original issue discount bonds, approximately 1.1% of the aggregate
principal amount of the Securities in the Trust (although only 0.4%* of the
aggregate bid price of all Securities in the Trust) are zero coupon bonds
(including bonds known as multiplier bonds, money multiplier bonds, capital
appreciation bonds, capital accumulator bonds, compound interest bonds, and
discount maturity payment bonds).
 
    The Securities in the Trust are insured to maturity by the insurance
obtained by the issuer from the following insurance companies: AMBAC: 10.6%*;
FSA: 17%*; MBIA: 72.4%*.
 
   Alternative Minimum Tax
 
    As of the date of the Summary of Essential Information, the Sponsor's
affiliate, the Prudential Investment Corporation, estimates that 29.2% of the
estimated annual income per unit consists of interest on private activity bonds,
which interest is to be treated as a tax preference item for alternative minimum
tax purposes (see 'Tax Status' and 'Schedule of Portfolio Securities.')
 
   New York Trust (Insured)
 
    The Portfolio contains 9 issues of Securities of issuers located in the
State of New York. One of the issues (21.5%* of the Trust) is a general
obligation of a governmental entity and is backed by the general taxing powers
of that entity. The remaining issues are payable from the income of specific
projects or authorities and are not supported by the issuer's power to levy
taxes. Although income to pay such Securities may be derived from more than one
source, the primary sources of such income and the percentage of issues deriving
income from such sources are as follows: health and hospital facilities: 24.6%*
of the Trust; education facilities: 23.8%* of the Trust; utility facilities:
21.1%* of the Trust; water and sewer facilities: 5.5%* of the Trust;
miscellaneous facilities: 3.5%* of the Trust.
 
    100%* of the Securities in the Trust are rated AAA by Standard & Poor's
Corporation. For a description of the meaning of the applicable rating symbols
as published by Standard & Poor's see Part B--'Bond Ratings.' It should be
emphasized, however, that the ratings of Standard & Poor's represent its opinion
as to the quality of the Securities which it undertakes to rate and that these
ratings are general and are not absolute standards of quality.
 
    Six Securities in the Trust have been issued with an 'original issue
discount.' (see Part B--'Tax Status.')

    Of these original issue discount bonds, approximately 8% of the aggregate
principal amount of the Securities in the Trust (although only 3.5%* of the
aggregate bid price of all Securities in the Trust) are zero coupon bonds
(including bonds known as multiplier bonds, money multiplier bonds, capital
appreciation bonds, capital accumulator bonds, compound interest bonds, and
discount maturity payment bonds).
 
    The Securities in the Trust are insured to maturity by the insurance
obtained by the issuer from the following insurance companies: AMBAC: 11.6%*;
FSA: 40%*; FGIC: 25.1%*; MBIA: 23.3%*.
 
   Alternative Minimum Tax
 
    As of the date of the Summary of Essential Information, the Sponsor's
affiliate, the Prudential Investment Corporation, estimates that 22% of the
estimated annual income per Unit consists of interest on private activity bonds,
which interest is to be treated as a tax preference item for alternative minimum
tax purposes (see 'Tax Status' and 'Schedule of Portfolio Securities.')
 
    The Sponsor participated as sole underwriter or manager or member of
underwriting syndicates from which approximately 51.4%* of the Trust was
acquired.

    (1) The Date of Deposit is the date on which the Indenture was signed and
the deposit of Securities with the Trustee was made.
    (2) This Public Offering Price is computed as of August 21, 1997 and may
vary from the Public Offering Price on the date of this Prospectus or any
subsequent date.
    (3) Includes Trustee's fee, Sponsor's Portfolio supervision fee, estimated
expenses and Evaluator's fees.
    (4) Exclusive of accrued interest which to August 26, 1997, the expected
date of settlement for the purchase of Units on August 21, 1997 was $15.97.
    (5) The estimated current return is increased for transactions entitled to a
reduced sales charge. (See Part B--'The Trust'--'Estimated Annual Income and
Current Return per Unit.')
    (6) The Estimated Current Return is calculated by dividing the Estimated Net
Annual Income per Unit by the Public Offering Price per Unit. The Estimated Net
Annual Income per Unit will vary with changes in fees and expenses of the
Trustee and the Evaluator and with the principal prepayment, redemption,
maturity, exchange or sale of Securities while the Public Offering Price will
vary with changes in the bid price of the underlying Securities; therefore,
there is no assurance that the present Estimated Current Return indicated above
will be realized in the future. The Estimated Long-Term Return is calculated on
a pre-tax basis using a formula which takes into consideration, and factors in
the relative weightings of, the market values, yields (which takes into account
the amortization of premiums and the accretion of discounts) and estimated
retirements of all of the Securities in the Trust and takes into account the
expenses and sales charge associated with each Unit. Since the market values and
estimated retirements of the Securities and the expenses of the Trust will
change, there is no assurance that the present Estimated Long-Term Return as
indicated above will be realized in the future. The after-tax Estimated
Long-Term Return will be lower to the extent of any taxation on the disposition
of Securities. The Estimated Current Return and Estimated Long-Term Return are
expected to differ because the calculation of the Estimated Long-Term Return
reflects the estimated date and amount of principal returned while the Estimated
Current Return calculations include only Net Annual Interest Income and Public
Offering Price as of the above indicated calculation date of the Summary of
Essential Information.

a pre-tax basis using a formula which takes into consideration, and factors in
the relative weightings of, the market values, yields (which takes into account
the amortization of premiums and the accretion of discounts) and estimated
retirements of all of the Securities in the Trust and takes into account the
expenses and sales charge associated with each Unit. Since the market values and
estimated retirements of the Securities and the expenses of the Trust will
change, there is no assurance that the present Estimated Long-Term Return as
indicated above will be realized in the future. The after-tax Estimated
Long-Term Return will be lower to the extent of any taxation on the disposition
of Securities. The Estimated Current Return and Estimated Long-Term Return are
expected to differ because the calculation of the Estimated Long-Term Return
reflects the estimated date and amount of principal returned while the Estimated
Current Return calculations include only Net Annual Interest Income and Public
Offering Price as of the above indicated calculation date of the Summary of
Essential Information.

             SPECIAL CONSIDERATIONS REGARDING CALIFORNIA SECURITIES
 
Risk Factors
 
    Potential purchasers of the Units of a State Trust should consider the fact
that the Trust's Portfolio consists primarily of Securities issued by the state
for which such State Trust is named or its municipalities or authorities and
realize the substantial risks associated with an investment in such Securities.
Each State Trust is subject to certain additional risk factors:
 
    The Sponsor believes the information summarized below describes some of the
more significant aspects of the State Trust. The sources of such information are
the official statements of issuers as well as other publicly available
documents. While the Sponsor has not independently verified this information, it
has no reason to believe that such information is not correct in all material
respects.
 
California Trust
 
    The State Trust will be affected by any political, economic or regulatory
developments affecting the ability of California issuers to pay interest or
repay principal on their obligations. Various developments regarding the
California Constitution and State statutes which limit the taxing and spending
authority of California governmental entities may impair the ability of
California issuers to maintain debt service on their obligations. The following
information constitutes only a brief summary and is not intended as a complete
description.
 
    In 1978, Proposition 13, an amendment to the California Constitution, was
approved, limiting real property valuation for property tax purposes and the
power of local governments to increase real property tax revenues and revenues
from other sources. Legislation adopted after Proposition 13 provided for
assistance to local governments, including their distribution of the
then-existing surplus in the General Fund, reallocation of revenues to local
governments, and assumption by State of certain local government obligations.
However, more recent legislation reduced such state assistance. There can be no
assurance that any particular level of State aid to local governments will be
maintained in future years. In Nordinger v. Hahn, the United States Supreme
Court upheld certain provisions of Proposition 13 against claims that it
violated the equal protection clause of the Constitution.
 
    In 1979, an amendment was passed adding Article XIIIB to the State
Constitution. As amended in 1990, Article XIIIB imposes an 'appropriations
limit' on the spending authority of the State and local government entities. In
general, the appropriations limit is based on certain 1978-79 expenditures,
adjusted annually to reflect changes in the cost of living, population and
certain services provided by State and local government entities. The
'appropriations limit' does not include appropriations for qualified capital
outlay projects, certain increases in transportation-related taxes, and certain
emergency appropriations.
 
    If a government entity raises revenues beyond its 'appropriation limit' in
any year, a portion of the excess which cannot be appropriated within the
following year's limit must be returned to the entity's taxpayers within two
subsequent fiscal years, generally by a tax credit, refund or temporary
suspension of tax rates or fee schedules. 'Debt service' is excluded from these
limitations, and is defined as 'appropriations required to ay the cost of
interest and redemption charges, including the funding of any reserve or sinking
fund required in connection therewith, on indebtedness existing or legally
authorized as of January 1, 1979 or on bonded indebtedness thereafter approved
[by the voters].' In addition, Article XIIIB requires the State Legislature to
establish a prudent State reserve, and to require the transfer of 50% of excess
revenue to the State School Fund; any amounts allocated to the State School Fund
will increase the appropriations limit.
 
    In 1986, California voters approved an initiative statute known as
Proposition 62. This initiative (i) requires that any tax for general
governmental purposes imposed by local governments be approved by resolution or
ordinance adopted by a two-thirds vote of the governmental entity's legislative
body and by a majority vote of the electorate of the governmental entity, (ii)
requires that any special tax) defined as tax levied for other than general
governmental purposes) imposed by local governmental entity be approved by a
two-thirds vote of the voters within that jurisdiction, (iii) restricts the use
of revenues from a special tax to the purposes or for the service for which the
special tax was imposed, (iv) prohibits the imposition of ad valorem taxes on
real property by local governmental entities except as permitted by the
Proposition 13 amendment, (v) prohibits the imposition of transaction taxes and
sales taxes on the sale of real property by local governments, (vi) requires
that any tax imposed by a local government on or after August 1, 1985, be
ratified by a majority vote of the electorate within two years of the adoption
of the initiative or be terminated by November 15, 1989,
 
                                     A-viii
 
<PAGE>
(vii) requires that, in the event a local government fails to comply with the
provisions of t his measure, a reduction of the amount of property tax revenue
allocated to such local government occurs in an amount equal to the revenues
received by such entity attributable to the tax levied in violation of the
initiative, and (viii) permits these provisions to be amended exclusively by the
voters of the State of California.
 
    In September 1995, the California Supreme court upheld the constitutionality
of Proposition 62, creating uncertainty as to the legality of certain local
taxes enacted by noncharter cities in California without voter approval. It is
not possible to predict the impact of the decision.
 
    In November 1988, California voters approved Proposition 98. This initiative
requires that revenues in excess of amount permitted to be spent and which would
otherwise be returned by revisions of tax rates or fee schedules, be transferred
and allocated (up to a maximum of 40%) to the State School Fund and be expended
solely for purposes of instructional improvement and accountability. No such
transfer or allocation of funds will be required if certain designated state
officials determine that annual student expenditures and class size meet certain
criteria as set forth in Proposition 98. All funds allocated to the State School
Fund shall cause the appropriation limits to be annually increased for any such
allocation made in the prior year. Proposition 98 also requires the State of
California to provide a minimum level of funding for public schools and
community colleges. The initiative permits the enactment of legislation, by a
two-thirds vote, to suspend the minimum funding requirement for one year.
 
    In November 1988, California voters approved Proposition 218. This
initiative applied the provisions of Proposition 62 to all entities, including
charter cities. It requires that all taxes for general purposes obtain a simple
majority popular vote and that taxes for special purposes obtain a two-thirds
majority vote. Prior to the effectiveness of Proposition 218, charter cities
could levy certain taxes such as transient occupancy taxes and utility user's
taxes without a popular vote. Proposition 218 will also limit the authority of
local governments to impose property-related assessments, fees and charges,
requiring that such assessments be limited to the special benefit conferred and
prohibiting their use for general governmental services. Proposition 218 also
allows voters to use their initiative power to reduce or repeal
previously-authorized taxes, assessments, fees and charges.
 
    Certain tax-exempt securities in which the State Trust may invest be
obligations payable solely from the revenues of specific institutions, or may be
secured by specific properties, which are subject to provisions of California
law that could adversely affect the holders of such obligations. For example,
the revenues of California health care institutions may be subject to state
laws, and California law limits the remedies of a creditor secured by a mortgage
or deed of trust on real property.
 
    From 1990 to 1993, California (the 'State') faced the worst economic, fiscal
and budget conditions since the 1930s. Construction, manufacturing (especially
aerospace), exports and financial services, among others, were severely
affected. Job losses were the worst of any post-war recession and have been
estimated to exceeded 800,000. California's economy has been recovering and
growing steadily stronger since the start of 1994. The rate of economic growth
in California in 1996, in terms of job gains, exceeded that of the rest of the
United States. The State added nearly 350,000 jobs during 1996, surpassing its
pre-recession employment peak of 12.7 million jobs. Another 380,000 jobs are
expected to be created in 1997. The unemployment rate, while still higher than
the national average, fell to the low 6 percent range in mid-1997, compared to
over 10 percent during the recession. Many of the new jobs were created in such
industries as computer services, software design, motion pictures and high
technology manufacturing. Business services, export trade and other
manufacturing also experienced growth. All major economic regions of the State
grew, with particularly large gains in the Silicon Valley region of Northern
California. Personal income grew by over 7 percent of $55 billion in 1996. The
residential construction sector of the State's economy remained weak in 1996,
with permits for new housing increasing modestly from the previous year. In
addition, the restructuring and consolidation occurring in California's
aerospace and financial services industries, while aimed at making the companies
involved more efficient and competitive in the longer term, has produced some
negative economic consequences in the shorter term, including uncertain job
outlook for many workers.
 
    The recession has affected State tax revenues, which mirror economic
conditions. It has also caused increased expenditures for health and welfare
programs. The State has also been facing a structural imbalance in its budget
with the largest programs supported by the General Fund (K-12 schools and
community colleges, health, welfare and corrections) growing at rates higher
than the growth rates for the principal revenue sources of the General Fund.
(The General Fund, the State's main operating fund, consists of revenues which
are not required to be credited to any other fund.) As a result, the State has
experienced recurring budget deficits. With the end of the recession, the
State's financial condition has
                                      A-ix
 
<PAGE>
improved in the 1995-96 and 1996-97 fiscal years, with a combination of better
than expected revenues, slowdown in growth of social welfare programs, and
continued spending restraint. As of June 30, 1997, the State's budget reserve
had a positive cash balance of $281 million. No deficit borrowing has occurred
at the end of the last two fiscal years and the State's cash flow borrowing was
limited to $3 billion in 1996-97.
 
    On December 6, 1994, Orange County, California (the 'County'), together with
its pooled investment funds (the 'Pools'), filed for protection under Chapter 9
of the federal Bankruptcy Code. On June 12, 1996, Orange County emerged from
bankruptcy after the successful sale of $880 million in municipal bonds allowed
the county to pay off the last of its creditors. On January 7, 1997, Orange
County returned to the municipal bond market with a $136 million bond issue
maturing in 13 years at an insured yield of 7.23 percent.
 
    Los Angeles County, the nation's largest county is also experiencing
financial difficulty. In August 1995 the credit rating of the County's long-term
bonds was downgraded for the third time since 1992 as a result of, among other
things, severe operating deficits for the County's health care system. In
addition, the County was affected by an ongoing loss of revenue caused by state
property tax shift initiatives in 1993 through 1995. In June, 1997, the Los
Angeles County Board of Supervisors approved an approximately $12 billion
1997-98 budget containing measures to eliminate a $157 million deficit. The
County's budgetary difficulties have continued and their effect, as well as the
effect of the improving California economy, on the 1997-1998 budget is still
uncertain.
 
   1997-98 Fiscal Year Budget
 
    On August 18, 1997, the Governor signed the 1997-98 Budget Act. The Budget
Act anticipates General Fund revenues and transfers of $52.5 billion (a 6.8
percent increase over the final 1996-97 levels), and expenditures of $52.8
billion (an 8.0 percent increase from the 1996-97 levels). On a budgetary basis,
the budget reserve (SFEU) is projected to decrease from $408 million at June 30,
1997 to $112 million at June 30, 1998. (The expenditure figure assumes
restoration of $200 million of vetoed funding.) The Budget Act also includes
Special Fund expenditures of $14.4 billion (as against estimated Special Fund
revenues of $14.0 billion), and $2.1 billion of expenditures from various Bond
Funds. Following enactment of the Budget Act, the State implemented its annual
cash flow borrowing program, issuing $3 billion of notes which mature on June
30, 1998.
 
The following are major features of the 1997-98 Budget Act:
 
    1. For the second year in a row, the Budget contains a large increase in
funding for K-14 education, reflecting strong revenues which have exceeded
initial budgeted amounts. Part of the nearly $1.75 billion in increased spending
is allocated to prior fiscal years.
 
    2. The Budget Act reflects a $1.235 billion pension case judgment payment,
and returns funding of the State's pension contribution to the quarterly basis
existing prior to the deferral actions invalidated by the courts. In May, 1997,
the California Supreme Court in PERS v. Wilson made final a judgment against the
State requiring an immediate payment from the General Fund to the Public
Employees Retirement Fund ('PERF') to make up certain deferrals in annual
retirement fund contributions which had been legislated in earlier years for
budget savings, and which the courts found to be unconstitutional. On July 30,
1997, at the Governor's direction, the Controller transferred $1.235 billion
from the General Fund to the PERF in satisfaction of the judgment, representing
the principal amount of the improperly deferred payments from 1995-96 and
1996-97. No provision exists for any additional payments relating to this court
case.
 
    3. Continuing the third year of a four-year 'compact' which the State
Administration has made with higher education units, funding from the General
Fund for the University of California and California State University has
increased by about 6 percent ($121 million and $107 million, respectively), and
there was no increase in student fees.
 
    4. Because of the effect of the pension payment, most other State programs
were continued at 1996-97 levels.
 
    5. Health and welfare costs are contained, continuing generally the grant
levels from prior years, as part of the initial implementation of the new
CalWORKs reform program.
                                      A-x
 
<PAGE>
    6. Unlike prior years, this Budget Act does not depend on uncertain federal
budget actions. About $300 million in federal funds, already included in the
federal FY 1997 and 1998 budgets, are included in the Budget Act, to offset
incarceration costs for illegal immigrants.
 
    7. The Budget Act contains no tax increases, and tax reductions. The Renters
Tax Credit was suspended for another year, saving approximately $500 million.
Subsequent to the adoption and signature of the Budget Act, the Governor
and Legislature reached certain agreements related to State expenditures and
taxes, including support, on an annual basis, for a $931 million (by full
implementation in the 1999-2000 fiscal year) tax cut aimed primarily at
middle income families but also including businesses, $80 million to provide
health insurance for uninsured children, $450 million to pay for county 
courts, $300 million for pay raises for State employees, and $52 million for 
tuition cuts for California public universities and community colleges.
These agreements mostly will affect budgets in future fiscal years and their
impact on the State's budget and the State's support for local governments
is uncertain.
 
    THE FOREGOING DISCUSSION OF THE 1997-98 FISCAL YEAR BUDGET IS BASED IN LARGE
PART ON STATEMENTS MADE IN A RECENT 'PRELIMINARY OFFICIAL STATEMENT' DISTRIBUTED
BY THE STATE OF CALIFORNIA. IN THAT DOCUMENT, THE STATE INDICATED THAT ITS
DISCUSSION OF THE FISCAL YEAR BUDGET IS BASED ON ESTIMATES AND PROJECTIONS OF
REVENUES AND EXPENDITURES FOR THE CURRENT FISCAL YEAR AND MUST NOT BE CONSTRUED
AS STATEMENTS OF FACT. THE STATE NOTED FURTHER THAT THE ESTIMATES AND
PROJECTIONS ARE BASED UPON VARIOUS ASSUMPTIONS WHICH MAY BE AFFECTED BY NUMEROUS
FACTORS, INCLUDING FUTURE ECONOMIC CONDITIONS IN THE STATE AND THE NATION, AND
THAT THERE CAN BE NO ASSURANCE THAT THE ESTIMATES WILL BE ACHIEVED.
 
   State Indebtedness
 
    As of August 1, 1997, the State had over $17.82 billion aggregate amount of
its general obligation bonds outstanding. General obligation bond authorizations
in an aggregate amount of approximately $8.26 billion remained unissued as of
August 1, 1997. The State also builds and acquires capital facilities through
the use of lease purchase borrowing. As of August 1, 1997, the State had
approximately $6.17 billion of outstanding Lease-Purchase Debt.
 
    In addition to the general obligation bonds, State agencies and authorities
had approximately $19.09 billion aggregate principal amount of revenue bonds and
notes outstanding as of June 30, 1997. Revenue bonds represent both obligations
payable from State revenue-producing enterprises and projects, which are not
payable from the General Fund, and conduit obligations payable only from
revenues paid by private users of facilities financed by such revenue bonds.
Such enterprises and projects include transportation projects, various public
works and exposition projects, educational facilities (including the California
State University and University of California systems), housing, health
facilities and pollution control facilities.
 
   Litigation
 
    The State is a party to numerous legal proceedings, many of which normally
occur in governmental operations. In addition, the State is involved in certain
other legal proceedings that, if decided against the State, might require the
State to make significant future expenditures or impair future revenue sources.
 
   Ratings
 
    Because of the State's continuing budget problems, the State's General
Obligation bonds were downgraded in July 1994 to A1 from Aa by Moody's, to A
from A+ by Standard & Poor's, and to A from AA by Fitch. All three rating
agencies expressed uncertainty in the State's ability to balance the budget by
1996. However, in 1996, citing California's improving economy and budget
situation, both Fitch and Standard & Poor's raised their ratings from A to A+.
 
    The Sponsor believes the information summarized above describes some of the
more significant aspects relating to the California Trust. The sources of such
information are Preliminary Official Statements and Official Statements relating
to the State's general obligation bonds and the State's revenue anticipation
notes, or obligations of other issuers located in the State of California, or
other publicly available documents. Although the Sponsor has not independently
verified this information, it has no reason to believe that such information is
not correct in all material respects.
 
                        SUPPLEMENT TO PART B--TAX STATUS
 
   California Tax Status
 
On the Date of Deposit, special California counsel for the Sponsor rendered an
opinion under the then existing California state income tax law which read as
follows:
 
    The Insured Trust is not an association taxable as a corporation under the
    income tax laws of the State of California;
 
                                      A-xi
 
<PAGE>
    The income, deductions and credits against tax of the Insured Trust will be
    treated as the income, deductions and credits against tax of the holders of
    Units in the Insured Trust under the income tax laws of the State of
    California;
 
    Interest on the bonds held by the Insured Trust to the extent that such
    interest is exempt from taxation under California law will not lose its
    character as tax-exempt income merely because that income is passed through
    to the holders of Units; however, a corporation subject to the California
    franchise tax is required to include that interest income in its gross
    income for purposes of determining its franchise tax liability;
 
    Each holder of a Unit in the Insured Trust will have a taxable event when
    the Insured Trust disposes of a bond (whether by sale, exchange, redemption,
    or payment at maturity) or when the Unit holder redeems or sells his Units.
    The total tax cost of each Unit to a holder of a Unit in the Insured Trust
    is allocated among each of the bond issues held in the Insured Trust (in
    accordance with the proportion of the Insured Trust comprised by each bond
    issue) in order to determine the holder's per Unit tax cost for each bond
    issue, and the tax cost reduction requirements relating to amortization of
    bond premium will apply separately to the per Unit tax cost of each bond
    issue. Therefore, under some circumstances, a holder of a Unit may realize
    taxable gain when the Insured Trust disposes of a bond or the holder's Units
    are sold or redeemed for an amount equal to or less than his original cost
    of the bond or Unit;
 
    Each holder of a Unit in the Insured Trust is deemed to be the owner of a
    pro rata portion of the Insured Trust under the personal property tax laws
    of the State of California;
 
    Each Unit holder's pro rata ownership of the bonds held by the Insured
    Trust, as well as the interest income therefrom, is exempt from California
    personal property taxes; and
 
    Amounts paid in lieu of interest on defaulted bonds held by the Trustee
    under policies of insurance issued with respect to such bonds will be
    excludable from gross income for California income tax purposes if, and to
    the same extent as, those amounts would have been so excludable if paid as
    interest by the respective issuer.
 
In the opinion of Messrs. Paul, Hastings, Janofsky & Walker, LLP, special 
California counsel to the Sponsor, no change in law has occurred since the 
Date of Deposit which would require a change in the above opinion.
 
   New York State
 
    The 1996-97 Executive Budget proposes $3.9 billion in actions to balance the
1996-97 Financial Plan. Before reflecting any actions proposed by the Governor
to restrain spending, General Fund disbursements for 1996-97 were projected at
$35 billion, an increase of $2.3 billion or 7 percent from 1995-96. This
increase would have resulted from growth in Medicaid, inflationary increases in
school aid, higher fixed costs such as pensions and debt service, collective
bargaining agreements, inflation, and the loss of non-recurring resources that
offset spending in 1995-96. Receipts would have been expected to fall by $1.6
billion. This reduction would have been attributable to modest growth in the
State's economy and underlying tax base, the loss of non-recurring revenues
available in 1995-96 and implementation of previously enacted tax reduction
programs.
 
    In recent years, State actions affecting the level of receipts and
disbursements, as well as the relative strength of the State and regional
economy, actions of the Federal government and other factors, have created
structural budget gaps for the State. These gaps resulted from a significant
disparity between recurring revenues and the cost of maintaining or increasing
the level of support for State programs. The 1995-96 enacted budget combines
significant tax and program reductions which will, in the current and future
years, lower both the recurring receipts base (before the effect of any economic
stimulus from such tax reductions) and the historical annual growth in state
program spending. Notwithstanding these changes, the State can expect to
continue to confront structural deficits in future years.
 
    The 1995-96 State Financial Plan includes actions that will have an effect
on the budget outlook for State fiscal year 1996-97 and beyond. The net amount
of nonrecurring resources used in the 1995-96 State Financial Plan is estimated
by the Division of the Budget at over $600 million. In addition to this use of
nonrecurring resources, the 1995-96 State Financial Plan reflects actions that
will directly affect the State's 1996-97 fiscal year baseline receipts and
disbursements. The three-year plan to reduce State personal income taxes will
decrease State tax receipts by an estimated $1.7 billion in State fiscal year
1996-97, in addition to the amount of reduction in State fiscal year 1995-96.
Further significant reductions in the personal income tax are scheduled for the
1997-98 State fiscal year. Other tax reductions enacted in 1994 and 1995 are
estimated to cause an additional reduction in receipts of over $500 million in
1996-97, as compared to the level of receipts in 1995-96. Similarly, many
actions taken to reduce disbursements in the State's 1995-96 fiscal year are
expected
                                     A-xii
 
<PAGE>
to provide greater reductions in State fiscal year 1996-97. These include
actions to reduce the State work force, reduce Medicaid and welfare expenditures
and slow community mental hygiene program development.
 
    The net impact of these and other factors is expected to produce a potential
imbalance in receipts and disbursements in State fiscal year 1996-97. The
Governor has indicated that in the 1996-97 Executive Budget he will propose to
close this potential imbalance primarily through General Fund expenditure
reductions and without increases in taxes or deferrals of scheduled tax
reductions.
 
    To address a potential imbalance in any given fiscal year, the State would
be required to take actions to increase receipts and/or reduce disbursements as
it enacts the budget for that year, and under the State Constitution, the
Governor is required to propose a balanced budget each year. To correct
recurring budgetary imbalances, the State would need to take significant actions
to align recurring receipts and disbursements in future fiscal years. There can
be no assurance, however that the Legislature will enact the Governor's
proposals or that the State's actions will be sufficient to preserve budgetary
balance in a given fiscal year or to align recurring receipts and disbursements
in future fiscal years.
 
    The State is a defendant in numerous legal proceedings and the monetary
damages sought are substantial. These proceedings could affect adversely the
financial condition of the State in the 1996-97 fiscal year or thereafter.
 
    The economic and financial condition of the State may be affected by various
financial, social, economic and political factors. Those factors can be very
complex, can vary from fiscal year to fiscal year, and are frequently the result
of actions taken not only by the State but also by entities, such as the federal
government, that are outside the State's control. Because of the uncertainty and
unpredictability of changes in these factors, their impact cannot be fully
included in the assumptions underlying the State's projections. There can be no
assurance that the State economy will not experience results that are worse than
predicted, with corresponding material and adverse effects on the State's
financial projections.
 
    From time to time, Federal expenditure reductions could reduce, or in some
cases eliminate, Federal funding of some local programs and accordingly might
impose substantial increased expenditure requirements on affected localities. If
the State, the City or any of the public authorities were to suffer serious
financial difficulties jeopardizing their respective access to the public credit
markets, the marketability of notes and bonds issued by localities within the
State could be adversely affected. Localities also face anticipated and
potential problems resulting from certain pending litigation, judicial decisions
and long-range economic trends. Long-range potential problems of declining urban
population, increasing expenditures and other economic trends could adversely
affect localities and require increasing State assistance in the future.
 
   New York City
 
    The fiscal health of the State is closely related to the fiscal health of
its localities, particularly The City of New York (the 'City'), which has
required and continues to require significant financial assistance from the
State which financial assistance could be affected by State revenue short-falls
or spending increases beyond its projections. For each of its 1981 through 1995
fiscal years, the City, as required by State law, achieved balanced operating
results, in accordance with GAAP.
 
    The New York State Financial Emergency Act for The City of New York (the
'Financial Emergency Act'), among other things, established the New York State
Financial Control Board (the 'Control Board') to oversee the City's financial
affairs. The City operates under a four-year financial plan which is prepared
annually and is updated quarterly. The City submits its financial plans as well
as the updates quarterly to the Control Board for its review. The Municipal
Assistance Corporation for The City of New York ('MAC') and the Office of the
State Deputy Comptroller for The City of New York ('OSDC') assist the Control
Board in exercising its powers and responsibilities and exercise various
monitoring functions relating to the City's financial position.
 
    During recent fiscal years, as a result of the slowing economy, the City
experienced significant shortfalls from earlier projections in almost all of its
major tax sources, and was required to take exceptional measures to close
substantial budget gaps in order to maintain balanced budgets. There can be no
assurance that the City will continue to maintain a balanced budget as required
by State law without additional tax or other revenue increases or additional
reductions in City services or entitlement programs, which could adversely
affect the City's economic base. The City's Financial Plan for the 1996-99
fiscal years, sets forth actions to close a projected budget gap of $3.1 billion
for the 1996 fiscal year. The Financial Plan also outlines projected budget gaps
of $2.0 billion, $3.3 billion and $4.1 billion for the 1997 through 1999 fiscal
years, respectively.
                                     A-xiii
 
<PAGE>
    As of June 30, 1995, the City estimated that its potential future liability
on account of outstanding claims against it amounted to approximately $2.5
billion and while the outcome of the proceedings and claims are not currently
predictable, adverse determinations in certain of them might have a material
adverse effect upon the City's ability to carry out the 1996-1999 Financial
Plan.
 
    On July 10, 1995, Standard and Poor's revised its rating of City bonds
downward to 'BBB+' and continued its negative rating outlook assessment. In
February 1991, Moody's Investors Service lowered its rating on the City's
general obligation bonds from 'A' to 'Baa1.'
 
    Over the long term, serious potential economic problems may continue to
aggravate State and local financial conditions. For decades, the State economy
has grown more slowly than the nation as a whole, resulting in the gradual
erosion of the State's relative economic affluence and tax base, and the
relocation of certain manufacturing operations and executive offices outside the
State. The causes of this relative decline are varied and complex, in many cases
involving national and international developments beyond the State's control.
Part of the reason for the long-term relative decline in the State economy has
been attributed to the combined state and local tax burden, which is among the
highest in the nation. The existence of this tax burden limits the State's
ability to impose higher taxes in the event of future financial difficulties.
 
    If during the existence of the New York Trust, the City, the State, or any
of its agencies or municipalities, because of its or their own financial
difficulties, become unable to meet regular commitments or if there should be a
default, moratorium or other interruption of payments of interest or principal
on any obligation issued by the City, the State, or a municipality or other
authority in New York State, the market value and marketability of Bonds in the
New York Trust, the asset value of Units of the New York Trust and the interest
income to the New York Trust, could be adversely affected.
 
New York Tax Status
 
In the opinion of Messrs. Cahill Gordon & Reindel, special New York counsel on
New York tax matters, as of the date of this Prospectus, under existing law:
 
    Interest on the underlying debt obligations which is exempt from tax under
    the laws of the State and City of New York when received by the New York
    Trust will retain its status as tax-exempt interest to its Unit Holders.
    (Interest on the underlying obligations in the New York Trust is, however,
    not excludable from income in determining the amount of the income-based (i)
    New York State franchise taxes on business and financial corporations or
    (ii) the New York City general corporation tax and the New York City
    financial corporation tax.) The minimum income taxes imposed by New York
    State and New York City on individuals, estates and trusts exclude from
    their taxable bases the Federal tax preference item with respect to
    tax-exempt interest.
 
    Non-residents of New York City will not be subject to the City personal
    income tax on gains derived with respect to their Units. Non-residents of
    the State will not be subject to New York State personal income tax on such
    gains unless the Units are employed in a business, trade or occupation
    carried on in New York State. A New York State or City resident should
    determine his basis and holding period for his Units in the same manner for
    New York State and City personal income tax purposes as for Federal income
    tax purposes.

THE UNIT HOLDERS, SPONSOR AND TRUSTEE
NATIONAL MUNICIPAL TRUST
SERIES 150 (Uninsured)
MULTISTATE SERIES 52
  consisting of:
    California Trust (Insured)
    New York Trust (Insured)

We have audited the statements of financial condition and schedules of 
portfolio securities of the National Municipal Trust, Series 150 (Uninsured) 
and Multistate Series 52 consisting of the California Trust (Insured) and 
the New York Trust (Insured) as of May 31, 1997, and the related statements 
of operations and changes in net assets for each of the three years in the 
period then ended.  These financial statements are the responsibility of the 
Trustee (see Footnote (a)(1)).  Our responsibility is to express an opinion 
on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing 
standards.  Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free 
of material misstatement.  An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements.  
Our procedures included confirmation of the securities owned as of May 31, 
1997, as shown in the statements of financial condition and schedules of 
portfolio securities by correspondence with The Chase Manhattan Bank, the 
Trustee.  An audit also includes assessing the accounting principles used 
and the significant estimates made by the Trustee, as well as evaluating the 
overall financial statement presentation.  We believe that our audits 
provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, 
in all material respects, the financial position of the National Municipal 
Trust, Series 150 (Uninsured) and Multistate Series 52 consisting of the 
California Trust (Insured) and the New York Trust (Insured) as of May 31, 
1997, and the results of their operations and the changes in their net 
assets for each of the three years in the period then ended in conformity 
with generally accepted accounting principles.

(a) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    The Trust is registered under the Investment Company Act of 1940 as a 
Unit Investment Trust.  The following is a summary of the significant 
accounting policies of the Trust:

(1) Basis of Presentation

    The Trustee has custody of and responsibility for all accounting and 
financial books, records, financial statements and related data of 
the Trust and is responsible for establishing and maintaining a 
system of internal controls directly related to, and designed to 
provide reasonable assurance as to the integrity and reliability 
of, financial reporting of the Trust.  The Trustee is also 
responsible for all estimates and accruals reflected in the Trust's 
financial statements.  The Evaluator determines the price for each 
underlying Security included in the Trust's Schedule of Portfolio 
Securities on the basis set forth in Part B of this Prospectus, 
"Public Offering of Units - Public Offering Price".  Under the 
Securities Act of 1933 ("the Act"), as amended, the Sponsor is 
deemed to be an issuer of the Trust Units.  As such, the Sponsor 
has the responsibility of an issuer under the Act with respect to 
financial statements of the Trust included in the Registration 
Statement under the Act and amendments thereto.

(2) Investments

    Investments are stated at market value as determined by the 
Evaluator based on the bid side evaluations on the last day of 
trading during the period, except that value on the date of deposit 
(June 23, 1992) represents the cost of investments to the Trust 
based on the offering side evaluations as of the date of deposit.

(3) Income Taxes

    The Trust is not an association taxable as a corporation for Federal 
income tax purposes; accordingly, no provision is required for such 
taxes.

(4) Expenses

    The Trust pays an annual Trustee's fee, estimated expenses, 
Evaluator's fees, and an annual Sponsor's portfolio supervision fee 
and may incur additional charges as explained under "Expenses and 
Charges" in Part B of this Prospectus.

(b) DISTRIBUTIONS

    Interest received by the Trust is distributed to the Unit Holders on or 
shortly after the twenty-fifth day of the month after deducting 
applicable expenses.  Receipts other than interest are distributed as 
explained in "Rights of Units Holders - Distribution of Interest and 
Principal" in Part B of this Prospectus.

(c) ORIGINAL COST TO INVESTORS

    The original cost to investors represents the aggregate initial public 
offering price as of the date of deposit (June 23, 1992) exclusive of 
accrued interest.


    A reconciliation of the original cost of Units to investors to the net 
amount applicable to investors as of May 31, 1997 follows:

<F1> All ratings are provided by Standard & Poor's Corporation, unless 
otherwise indicated.  A brief description of applicable Security 
ratings is given under "Bond Ratings" in Part B of this Prospectus.

<F2> There is shown under this heading the date on which each issue of 
Securities is redeemable by the operation of optional call 
provisions and the redemption price for that date; unless otherwise 
indicated, each issue continues to be redeemable at declining 
prices thereafter but not below par.  Securities listed as non-
callable, as well as Securities listed as callable, may also be 
redeemable at par under certain circumstances from special 
redemption payments.

<F3> There is shown under this heading the date on which an issue of 
Securities is subject to scheduled sinking fund redemption and the 
redemption price on such date.

<F4> The market value of the Securities as of May 31, 1997 was determined 
by the Evaluator on the basis of bid side evaluations for the 
Securities on the last trading date during the period (May 30, 
1997).

<F5> At May 31, 1997, the net unrealized market appreciation of all 
Securities was comprised of the following:

<TABLE>
       <S>                                         <C>
       Gross unrealized market appreciation         $387,368
       Gross unrealized market depreciation          (47,397)
       Net unrealized market appreciation           $339,971
</TABLE>

    The amortized cost of the Securities for Federal income tax purposes 
was $8,550,040 at May 31, 1997.

<F6> In the opinion of bond counsel to the issuing governmental 
authorities, interest payments on these bonds will be a tax 
preference item for individuals and corporations for alternative 
minimum tax purposes.  Normally, the bonds pay interest 
semiannually.  The payment dates can generally be determined based 
on the date of maturity, i.e., a bond maturing on December 1 will 
pay interest semiannually on June 1 and December 1.  See "Tax 
Status" in Part B of this Prospectus.

<F7> Moody's Investors Service, Inc. rating.

<F8> The Issuers of Portfolio Nos. 8 and 9 have indicated that they will 
refund these Securities on their respective optional redemption 
dates.

<F9> Insurance to maturity has been obtained by the Issuer from the
listed Insurance company.  The "AAA" rating on this Security is
based in part on the creditworthiness and claims-paying ability of
the Insurance Company insuring such security to maturity.

(a) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    The Trust is registered under the Investment Company Act of 1940 as a 
Unit Investment Trust.  The following is a summary of the significant 
accounting policies of the Trust:

(1) Basis of Presentation

    The Trustee has custody of and responsibility for all accounting and 
financial books, records, financial statements and related data of 
the Trust and is responsible for establishing and maintaining a 
system of internal controls directly related to, and designed to 
provide reasonable assurance as to the integrity and reliability 
of, financial reporting of the Trust.  The Trustee is also 
responsible for all estimates and accruals reflected in the Trust's 
financial statements.  The Evaluator determines the price for each 
underlying Security included in the Trust's Schedule of Portfolio 
Securities on the basis set forth in Part B of this Prospectus, 
"Public Offering of Units - Public Offering Price".  Under the 
Securities Act of 1933 ("the Act"), as amended, the Sponsor is 
deemed to be an issuer of the Trust Units.  As such, the Sponsor 
has the responsibility of an issuer under the Act with respect to 
financial statements of the Trust included in the Registration 
Statement under the Act and amendments thereto.

(2) Investments

    Investments are stated at market value as determined by the 
Evaluator based on the bid side evaluations on the last day of 
trading during the period, except that value on the date of deposit 
(June 23, 1992) represents the cost of investments to the Trust 
based on the offering side evaluations as of the date of deposit.

(3) Income Taxes

    The Trust is not an association taxable as a corporation for Federal 
income tax purposes; accordingly, no provision is required for such 
taxes.

(4) Expenses

    The Trust pays an annual Trustee's fee, estimated expenses, 
Evaluator's fees, and an annual Sponsor's portfolio supervision fee 
and may incur additional charges as explained under "Expenses and 
Charges" in Part B of this Prospectus.

                                May 31, 1997

(b) DISTRIBUTIONS

    Interest received by the Trust is distributed to the Unit Holders on or 
shortly after the twenty-fifth day of the month after deducting 
applicable expenses.  Receipts other than interest are distributed as 
explained in "Rights of Units Holders - Distribution of Interest and 
Principal" in Part B of this Prospectus.

(c) ORIGINAL COST TO INVESTORS

    The original cost to investors represents the aggregate initial public 
offering price as of the date of deposit (June 23, 1992) exclusive of 
accrued interest.


    A reconciliation of the original cost of Units to investors to the net

                              May 31, 1997

<F10> All ratings are provided by Standard & Poor's Corporation.  A brief 
description of applicable Security ratings is given under "Bond 
Ratings" in Part B of this Prospectus.

<F11> There is shown under this heading the date on which each issue of 
Securities is redeemable by the operation of optional call 
provisions and the redemption price for that date; unless otherwise 
indicated, each issue continues to be redeemable at declining 
prices thereafter but not below par.  Securities listed as non-
callable, as well as Securities listed as callable, may also be 
redeemable at par under certain circumstances from special 
redemption payments.

<F12> There is shown under this heading the date on which an issue of 
Securities is subject to scheduled sinking fund redemption and the 
redemption price on such date.

<F13> The market value of the Securities as of May 31, 1997 was determined 
by the Evaluator on the basis of bid side evaluations for the 
Securities on the last trading date during the period (May 30, 
1997).

<F14> At May 31, 1997, the unrealized market appreciation of all 
Securities was comprised of the following:

<TABLE>
       <S>                                         <C>
       Gross unrealized market appreciation         $121,735
       Gross unrealized market depreciation             -   
       Unrealized market appreciation               $121,735
</TABLE>

    The amortized cost of the Securities for Federal income tax purposes 
was $1,999,660 at May 31, 1997.

<F15> Insurance to maturity has been obtained by the Issuer from the 
listed Insurance Company for the Securities.  The "AAA" ratings on 
these Securities are based in part on the creditworthiness and 
claims-paying ability of the Insurance Company insuring such 
Security to maturity.  No premium is payable therefore by the 
Trust.

<F16> In the opinion of bond counsel to the issuing governmental 
authorities, interest payments on these bonds will be a tax 
preference item for individuals and corporations for alternative 
minimum tax purposes.  Normally, the bonds pay interest 
semiannually.  The payment dates can generally be determined based 
on the date of maturity, i.e., a bond maturing on December 1 will 
pay interest semiannually on June 1 and December 1.  See "Tax 
Status" in Part B of this Prospectus.

(a) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    The Trust is registered under the Investment Company Act of 1940 as a 
Unit Investment Trust.  The following is a summary of the significant 
accounting policies of the Trust:

(1) Basis of Presentation

    The Trustee has custody of and responsibility for all accounting and 
financial books, records, financial statements and related data of 
the Trust and is responsible for establishing and maintaining a 
system of internal controls directly related to, and designed to 
provide reasonable assurance as to the integrity and reliability 
of, financial reporting of the Trust.  The Trustee is also 
responsible for all estimates and accruals reflected in the Trust's 
financial statements.  The Evaluator determines the price for each 
underlying Security included in the Trust's Schedule of Portfolio 
Securities on the basis set forth in Part B of this Prospectus, 
"Public Offering of Units - Public Offering Price".  Under the

based on the offering side evaluations as of the date of deposit.

<F17> All ratings are provided by Standard & Poor's Corporation.  A brief 
description of applicable Security ratings is given under "Bond 
Ratings" in Part B of this Prospectus.


<F18> There is shown under this heading the date on which each issue of
Securities is redeemable by the operation of optional call 
provisions and the redemption price for that date; unless otherwise 
indicated, each issue continues to be redeemable at declining 
prices thereafter but not below par.  Securities listed as non-
callable, as well as Securities listed as callable, may also be 
redeemable at par under certain circumstances from special 
redemption payments.

<F19> There is shown under this heading the date on which an issue of 
Securities is subject to scheduled sinking fund redemption and the 
redemption price on such date.

<F20> The market value of the Securities as of May 31, 1997 was determined 
by the Evaluator on the basis of bid side evaluations for the 
Securities on the last trading date during the period (May 30, 
1997).

<F21> At May 31, 1997, the unrealized market appreciation of all 
Securities was comprised of the following:

<TABLE>
       <S>                                         <C>
       Gross unrealized market appreciation         $199,077
       Gross unrealized market depreciation             -   
       Unrealized market appreciation               $199,077
</TABLE>

    The amortized cost of the Securities for Federal income tax purposes 
was $3,602,174 at May 31, 1997.

<F22> In the opinion of bond counsel to the issuing governmental 
authorities, interest payments on these bonds will be a tax 
preference item for individuals and corporations for alternative 
minimum tax purposes.  Normally, the bonds pay interest 
semiannually.  The payment dates can generally be determined based 
on the date of maturity, i.e., a bond maturing on December 1 will 
pay interest semiannually on June 1 and December 1.  See "Tax 
Status" in Part B of this Prospectus.

<F23> Insurance to maturity has been obtained by the Issuer from the 
listed Insurance Company for the Securities.  The "AAA" ratings on 
these Securities are based in part on the creditworthiness and 
claims-paying ability of the Insurance Company insuring such 
Security to maturity.  No premium is payable therefore by the 
Trust.

               Re:  National Municipal Trust,
                    Multistate Series 52_____

Ladies and Gentlemen:

          Pursuant to your request, we have reviewed the opinion expressed
by prior California counsel to you regarding certain California income and
property tax matters with respect to National Municipal Trust Multistate
Series 52.  We are of the opinion that such opinion, a copy of which is set
forth in the Prospectus comprising a part of Post-Effective Amendment No. 5
to the Form S-6 Registration Statement of National Municipal Trust, Series
150 and Multistate Series 52 (SEC File No. 33-47975), remains valid, that
no change has occurred which would require a change to such opinion, and
that you may rely on it in connection with the filing of such
Post-Effective Amendment.

          We consent to the use of our name under the caption "California
Tax Status" in such Prospectus and to the filing of this opinion as an
exhibit to such Post-Effective Amendment.

                              Very truly yours,

                              Paul, Hastings, Janofsky & Walker
