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 (or intermediate 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 trust composing Multistate
Series 50 designated as the New York Trust (Insured (Intermediate Term)) (the
'New York Trust (Insured (Intermediate Term))' or the 'State Trust') (the
'Trusts' or the 'Trust' 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 the Insured Trust is covered by an
irrevocable insurance policy as a result of which the Units of the 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 New York Trust (Insured (Intermediate Term)) 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 148 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 148 ('National Trust (Uninsured)') and
Multistate Series 50 which consists of one underlying unit investment trust
designated as the New York Trust (Insured (Intermediate Term)) (the 'New York
Trust (Insured (Intermediate Term))' or the 'State Trust') (the 'Trusts' or the
'Trust' or the 'Insured Trust' as the context requires) are composed of
interest-bearing municipal bonds (the 'Securities'). The Securities in the State
Trust 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
Trust, 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 portfolio of the Insured Trust 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
('CGIC'), 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 the Insured Trust have received a rating of 'AAA' by Standard &
Poor's Corporation. There can be no assurance that Units of the Insured Trust
will retain this 'AAA' rating. There is, of course, no guarantee that the
objectives of the Insured Trust 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
(or intermediate 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 element of market value in regard to the
Securities thus insured. The insurance on the Securities in the New York Trust
(Insured (Intermediate Term)) does not protect Unit Holders from the risk that
the
A-i
<PAGE>
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 seventh paragraph on page B-7 in Part B is amended to delete such
paragraph and replace it with the following:
The Puerto Rican economy is affected by a number of Commonwealth and Federal
investment incentive programs. For example, prior to 1996, Section 936 of the
Internal Revenue Code generally provided deferral of Federal income taxes for
U.S. companies operating on the island until profits are repatriated. Section
936 was repealed by the Small Business Job Protection Act of 1996. It is
expected that the repeal of Section 936 will have a strongly negative impact on
Puerto Rico's economy.
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 14 issues of Securities of issuers located in 10
states and two in Puerto Rico. One of the issues (1.8%* 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: airport facilities: 13.9%* of
the Trust; education facilities: 6.1%* of the Trust; health and hospital
facilities: 37.4%* of the Trust; housing facilities: 26.9%* of the Trust;
utility facilities: 7.2%* of the Trust; special tax bonds: 6.7%* of the Trust.
The Trust is concentrated in health and hospital facilities Securities and
housing facilities Securities.
The Portfolio also contains Securities representing 21.1%* 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 21.1%* 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.
- ------------
* Percentages computed on the basis of the aggregate bid price of the
Securities in the Trust on July 23, 1997.
A-ii
<PAGE>
51.3%* of the Securities in the Trust are rated by Standard & Poor's
Corporation (16.4%* being rated AAA, 14.2%* being rated AA, 7.9%* being rated A
and 12.8%* being rated BBB) and 48.7%* of the Securities in the Trust are rated
by Moody's Investors Service (6.7%* being rated Aaa, 12.9%* being rated Aa,
15.2%* being rated A and 13.9% 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.
Seven Securities in the Trust have been issued with an 'original issue
discount.' (See Part B--'Tax Status.')
Of these original issue discount bonds, approximately 9.1% of the aggregate
principal amount of the Securities in the Trust (although only 3.1%* 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 39.1% 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 7.8%* of the Trust was
acquired.
New York Trust (Insured (Intermediate Term))
The Portfolio contains 10 issues of Securities of issuers located in the
State of New York. Four of the issues (37.2%* of the Trust) are general
obligations of governmental entities and are backed by the general taxing powers
of those entities. 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: lease facilities: 23.9%* of the Trust;
transportation facilities: 38.9%* of the Trust. The Trust is concentrated in
general obligations and transportation facilities Securities.
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.
Five Securities in the Trust have been issued with an 'original issue
discount.' (See Part B--'Tax Status.')
Of these original issue discount bonds, approximately 6.0% of the aggregate
principal amount of the Securities in the Trust (although only 4.4%* 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: FGIC: 15.3%*;
FSA: 10.5%*; MBIA: 74.2%*.
Alternative Minimum Tax
As of the date of the Summary of Essential Information, the Sponsor's
affiliate, The Prudential Investment Corporation, estimates that 12.0% of the
estimated net 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 21.4%* 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 July 23, 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 July 28, 1997, the expected date
of settlement for the purchase of Units on July 23, 1997 was $16.54.
(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.

(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

there is no assurance that the present Estimated Current Return indicated above

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.

Risk Factors
Potential purchasers of the Units of the New York Trust should consider the
fact that the New York Trust's portfolio consists primarily of securities issued
by the State of New York (the 'State') or its municipalities or authorities and
realize the substantial risks associated with an investment in such securities.
The Sponsor believes the information summarized below describes some of the
more significant aspects of the New York Trust. The sources of such information
are the official statements of issuers. 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.
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 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 1995-96 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.
A-vi
<PAGE>
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.
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
A-vii
<PAGE>
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.

(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
(May 5, 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.

April 30, 1997
(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
(May 5, 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.

<F1> 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.
<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 that date.
<F4> The market value of the Securities as of April 30, 1997 was
determined by the Evaluator on the basis of bid side evaluations
for the Securities on that date.
<F5> At April 30, 1997, the unrealized market appreciation of all
Securities was comprised of the following:
<TABLE>
<S> <C>
Gross unrealized market appreciation $152,530
Gross unrealized market depreciation -
Unrealized market appreciation $152,530
</TABLE>
The amortized cost of the Securities for Federal income tax purposes
was $4,311,052 at April 30, 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> 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.
<F8> The Issuers of Portfolio Nos. 4 and 6 have indicated that they will
refund these Securities on their respective optional redemption
dates.
