The initial public offering of Units in the 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 the 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 of long-term debt obligations
issued on behalf of states, counties, municipalities, authorities and political
subdivisions thereof, and territories, or possessions of the United States, and
the conservation of capital. There is, of course, no guarantee that the Trust's
objectives will be achieved. The value of the Units of the Trust will fluctuate
with the value of the portfolio of underlying Securities. The Securities in the
Trust are not insured by The Prudential Insurance Company of America. The
Prospectus indicates the extent to which interest income of the 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 the Trust is equal to the aggregate bid
side evaluation of the underlying Securities in the 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 175 (the 'National Trust' or the 'Trust' as
the context requires) is composed of interest-bearing municipal bonds (the
'Securities'). 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). The Securities in the Trust were, as of the Date
of Deposit rated in the category of 'BBB' or better by Standard & Poor's
Corporation or Fitch Investors Service, Inc. or 'Baa' or better by Moody's
Investors Service. (See Part B--'Bond Ratings.')
MONTHLY DISTRIBUTIONS of principal, premium, if any, and interest received
by the 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. In some
cases, distribution on a semi-annual basis may be available. (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 the 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.' 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 the 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. (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, a decline
in creditworthiness of the issuer of said Securities.
Note: In Part B 'Trustee' the location of the unit investment trust office
of The Chase Manhattan Bank is amended to read 4 New York Plaza, New York, New
York 10004.
Note: The second paragraph in Part B 'Sponsor' is amended to delete such
paragraph and replace it with the following:

Portfolio Summary
National Trust
The Portfolio contains 12 issues of Securities of issuers located in 11
states. 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: education facilities: 1.3%* of the Trust; health
and hospital facilities: 31.1%* of the Trust; housing facilities: 15.6%* of the
Trust; industrial revenue facilities: 20.3%* of the Trust; lease facilities:
10.4%* of the Trust; power facilities: 11.1%* of the Trust; resource recovery
facilities: 10.2 %* of the Trust. The Trust is concentrated in health and
hospital facilities Securities.
The Portfolio also contains Securities representing 15.6%* of the Trust
(single-family housing securities) which are subject to the requirements of
Section 103A of the Internal Revenue Code of 1954 or Section 143 of the Internal
Revenue Code of 1986, as amended.
Approximately 15.6% 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.
79.0%* of the Securities in the Trust are rated by Standard & Poor's
Corporation (1.3%* being rated AAA, 14.7%* being rated AA and 63.0%* being rated
A) and 21.0%* of the Securities in the Trust are rated A by Moody's Investors
Service. 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.
Ten 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 1.3%* 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
The Sponsor's affiliate, The Prudential Investment Corporation, estimates
that 48.5% 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.')

(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 May 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 May 29, 1997, the expected date
of settlement for the purchase of Units on May 23, 1997 was $3.90.
(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.

<AUDIT-REPORT>
INDEPENDENT AUDITORS' REPORT
THE UNIT HOLDERS, SPONSOR AND TRUSTEE
NATIONAL MUNICIPAL TRUST
SERIES 175
We have audited the statement of financial condition and schedule of
portfolio securities of the National Municipal Trust Series 175 as of
February 28, 1997, and the related statements of operations and changes in
net assets for the year ended February 28, 1997 and for the period from
March 1, 1995 (date of deposit) to February 29, 1996. 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
February 28, 1997 as shown in the statement of financial condition and
schedule 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 175 as of February 28, 1997, and the results of its operations
and the changes in its net assets for the year ended February 28, 1997 and
for the period from March 1, 1995 (date of deposit) to February 29, 1996 in
conformity with generally accepted accounting principles.

SERIES 175
February 28, 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
(March 1,1995) 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.
