SUMMARY OF ESSENTIAL INFORMATION
(Continued)
THE TRUST -- The Dean Witter Select Municipal Trust,
Insured National Portfolio Series 41 (the "Trust") is a unit
investment trust which was created on May 25, 1993 (the "Date
of Deposit"), under the laws of the State of New York pursuant
to an Indenture as defined in Part B. The Trust is composed
of "investment grade" long-term, interest-bearing municipal
bonds (the "Securities"). (For a description of the meaning
of "investment grade" securities, see: "Bond Ratings", in
Part B.) The objectives of the Trust are: (1) the receipt of
income which, under existing law, is excludable from gross
income for Federal income tax purposes (except in certain
instances depending on the Unit Holders) and (2) the
conservation of capital. The payment of interest and the
preservation of principal of the Trust is dependent on the
continuing ability of the respective Issuers of the Securities
or the bond insurers thereof to meet their obligations to pay
principal and interest on the Securities. Therefore, there is
no guarantee that the objectives of the Trust will be
achieved. All of the Securities in the Portfolio are
obligations of states or of the counties, municipalities or
public authorities thereof. Interest on the Securities, in
the opinion of bond counsel or special tax counsel to the
Issuers thereof, under existing law, is excludable from gross
income for Federal income tax purposes (except in certain
instances depending on the Unit Holders). (For a discussion
of certain tax aspects of the Trust, see: "Tax Status", in
Part B.)
OFFERS TO SELL OR THE SOLICITATION OF ORDERS TO BUY
MAY ONLY BE MADE IN THOSE JURISDICTIONS IN WHICH THE UNITS OF
THE TRUST HAS BEEN REGISTERED. INVESTORS SHOULD CONTACT
ACCOUNT EXECUTIVES OF THE SPONSOR TO DETERMINE WHETHER THE
UNITS OF THIS TRUST HAVE BEEN REGISTERED FOR SALE IN THE STATE
IN WHICH THEY RESIDE.
INSURANCE -- A policy of insurance guaranteeing the
scheduled payment of principal and interest ("Bond Insurance")
has been obtained from the bond insurers indicated on the
respective "Schedule of Portfolio Securities", herein, and
paid for by the Issuers of the Securities, or by third
parties, for all the Securities in the Insured National Trust.
The policies of Bond Insurance are non-cancelable and cover
default in the payment of principal and interest on the
Securities so insured so long as such Securities remain
outstanding. Bond Insurance on all Securities in the Insured
National Trust relates only to the Securities in such Insured
National Trust and not to the
A-4
<PAGE>
-5-
Units offered hereby. No representation is made herein as to
any bond insurer's ability to meet its obligations under a
policy of Bond Insurance relating to a Security in the Insured
National Trust. However, as a result of such Bond Insurance,
the Securities, as well as the Units of the Insured National
Trust, are rated "AAA" by Standard & Poor's Corporation.
There can be no assurance that such "AAA" ratings will be
retained. (See: "Insurance on the Securities in an Insured
Trust", in Part B.)
MONTHLY DISTRIBUTIONS -- Monthly distributions of
principal, premium, if any, and interest received by the Trust
will be made on or shortly after the fifteenth day of each
month to Unit Holders of record on the ninth day of such month.
Alternatively, Unit Holders may elect to have their monthly
distributions reinvested in either of the Reinvestment Programs
of the Sponsor, neither of which are insured. (See:
"Reinvestment Programs", in Part B.)
PUBLIC OFFERING PRICE -- The Public Offering Price
per Unit of each Trust is calculated daily, and is equal to the
aggregate bid side evaluation of the underlying Securities,
divided by the number of Units outstanding, plus a sales charge
calculated by reference to "Sales Charge/Volume Discount",
below, plus the per Unit balance in the Interest and Principal
Accounts. Units are offered at the Public Offering Price, plus
accrued interest. (See: "Public Offering of Units", in Part
B.)
ESTIMATED CURRENT RETURN -- The Estimated Current
Return shows the return based on the Public Offering Price and
is computed by multiplying the estimated net annual interest
rate per Unit (which shows the return based on a $1,000 face
amount) by $1,000 and dividing the result by the Public
Offering Price (not including accrued interest). The net
annual interest rate per Unit will vary with changes in the
fees and expenses of the Trustee, the Sponsor and the Evaluator
and with the exchange, redemption, sale or maturity of the
underlying Securities. In addition, the Public Offering Price
will also vary with fluctuations in the bid side evaluation of
the underlying Securities. Therefore, it can be expected that
the Estimated Current Return will fluctuate in the future.
(See: "The Units -- Estimated Annual Income and Current
Return", in Part B.)
MARKET FOR UNITS -- The Sponsor, though not obligated
to do so, intends to maintain a market for the Units based on
the aggregate bid side evaluation of the underlying Securities,
A-5
<PAGE>
-6-
as more fully described in Part B -- "Public Offering of Units
- Secondary Market". If such market is not maintained, a Unit
Holder will be able to dispose of its Units through redemption
at prices based on the aggregate bid side evaluation of the
underlying Securities. (See: "Redemption", in Part B.)
Market conditions may cause such prices to be greater or less
than the amount paid for Units.
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 or intermediate
term debt obligations may entail, including the risk that the
value of the Units will decline with increases in interest
rates. The Insured National Trust is considered to be
concentrated in Electric and Power Securities and Health Care
and Hospital Securities 39.85% and 29.47%, respectively, of the
aggregate market value of the Insured National Trust
Portfolio). (See: "The Trust -- Special Considerations" and
"The Trust -- Summary Description of the Portfolios", in
Part B. See also: "The Insured National Trust", herein, for a
discussion of additional risks relating to Units of the Trust.)
OTHER INFORMATION -- The Securities in the Portfolio
of the Trust were chosen in part on the basis of their
respective maturity dates. A long term Trust contains
obligations maturing in 15 years or more from the Date of
Deposit. The maturity date of the Trust is January 1, 2042.
The latest maturity of a Security in the Insured National Trust
is January 2033; and the average life to maturity (or date of
pre-refunding of a bond) of the Portfolio of Securities therein
is 25.971 years. The actual maturity dates of the Securities
contained in the Trust are shown on the "Schedule of Portfolio
Securities", herein.
The Trustee shall receive annually 75 cents per
$1,000 principal amount of Securities in the Trust for its
services as Trustee. See: "Expenses and Charges", in Part B,
for a description of other fees and charges which may be
incurred by a Trust.
SALES CHARGE/VOLUME DISCOUNT -- The Public Offering
Price per Unit will be computed by dividing the aggregate of
the bid prices of the Securities in a Trust by the number of
Units outstanding and then adding the appropriate sales charge
described below. The sales charge will reflect different rates
depending upon the maturities of the various underlying
A-6
<PAGE>
-7-
Securities. The sales charge per Unit in the secondary market
(the "Effective Sales Charge") will be computed by multiplying
the Evaluator's determination of the bid side evaluation of
each Security by a sales charge determined in accordance with
the table set forth below based upon the number of years
remaining to the maturity of each such Security, totalling all
such calculations, and dividing this total by the number of
Units then outstanding. In calculating the date of maturity, a
Security will be considered to mature on its stated maturity
date unless: (a) the Security has been called for redemption
or funds or securities have been placed in escrow to redeem it
on an earlier call date, in which case the call date will be
deemed the date on which such Security matures; or (b) the
Security is subject to a mandatory tender, in which case the
mandatory tender date will be deemed the date on which such
Security matures.

day of the specified number of Units of a Trust set forth
below.

To qualify for the reduced sales charge and
concession applicable to quantity purchases, the selling dealer
must confirm that the sale is to a single purchaser, as
described in "Volume Discount" in Part B of the Prospectus.
Units purchased at an Effective Sales Charge (before
volume purchase discount) of less than 3.00% of the Public
Offering Price (3.093% of the bid side evaluation of the
Securities) will not be eligible for exchange at a reduced
sales charge described under the Exchange Option.
Dealers purchasing certain dollar amounts of Units
during the life of the Trusts may be entitled to additional
concessions. The Sponsor reserves the right, at any time and
from time to time, to change the level of dealer concessions.
For further information regarding the volume
discount, see: "Public Offering of Units -- Volume Discount",
in Part B.

Issuers located in six states and one of which (approximately
13.11% of the aggregate market value of the Insured National
Trust Portfolio) was issued by an Issuer located in the
District of Columbia. Two issues of Securities are each a
general obligation of an Issuer. 86.89% issues of Securities,
while not backed by the taxing power of the Issuer, are payable
from revenues or receipts derived from specific projects or
other available sources. The Insured National Trust contains
the following categories of Securities:
Percentage of Aggregate

Portfolios", in Part B, for a summary of the investment risks
associated with the type of Securities contained in the Insured
National Trust. See: "Tax Status", in Part B, for a
discussion of certain tax considerations with regard to

National Trust, approximately 3.27% of the aggregate principal
amount of the Securities in the Insured National Trust (or .97%
of the market value of all Securities in the Insured National
Trust on June 6, 1997) are zero coupon bonds (including bonds
known as multiplier bonds, money multiplier bonds, capital

aggregate market value of the Securities in the Insured
National Trust was $3,786,154.35.

National Trust were rated "AAA" by Standard & Poor's
Corporation because of the Bond Insurance policies issued in
respect of such Securities. (See: the respective "Schedule of
Portfolio Securities", herein, and "Bond Ratings", in Part B.)
A Security in the Portfolio may subsequently cease to be rated
or the rating assigned may be reduced below the minimum
requirements of the Insured National Trust for the acquisition
of Securities. While such events may be considered by the
Sponsor in determining whether to direct the Trustee to dispose
of the Security (see: "Sponsor -- Responsibility", in Part B),
such events do not automatically require the elimination of
such Security from the Portfolio.

INDEPENDENT AUDITORS' REPORT
THE UNIT HOLDERS, SPONSOR AND TRUSTEE
DEAN WITTER SELECT MUNICIPAL TRUST
INSURED NATIONAL PORTFOLIO SERIES 41
We have audited the statement of financial condition and schedule of
portfolio securities of the Dean Witter Select Municipal Trust Insured
National Portfolio Series 41 as of April 30, 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 April 30,
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 Dean Witter Select
Municipal Trust Insured National Portfolio Series 41 as of April 30, 1997,
and the results of its operations and the changes in its net assets for each
of the three years in the period then ended in conformity with generally
accepted accounting principles.

based on the offering side evaluations as of the date prior to 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

Re: Dean Witter Select Municipal Trust,
Insured National Portfolio Series 41
Gentlemen:
It is our understanding that you are filing with the
Securities and Exchange Commission a Post Effective Amendment to
the above captioned trust, SEC file number 33-27810.
Since the portfolio is composed solely of securities
covered by bond insurance policies that insure against default in
the payment of principal and interest on the securities for so
long as they remain outstanding and such policies have been
issued by one or more insurance companies which have been
assigned "AAA" claims paying ability ratings by Standard &
Poor's, we reaffirm the assignment of a "AAA" rating to the units
of the trust and a "AAA" rating to the securities contained in
the trust.
You have permission to use the name of Standard &
Poor's Ratings Services, a division of The McGraw-Hill Companies,
Inc. and the above-assigned ratings in connection with your
dissemination of information relating to these units, provided
that it is understood that the ratings are not "market" ratings
nor recommendations to buy, hold, or sell the units of the trust
or the securities in the trust. Further, it should be understood
that the rating on the units does not take into account the
extent to which fund expenses or portfolio asset sales for less
than the fund's purchase price will reduce payment to the unit
holders of the interest and principal required to be paid on the
portfolio assets. Standard & Poor's reserves the right to advise
its own clients, subscribers, and the public of the ratings.
<PAGE>
-2-
Standard & Poor's relies on the sponsor and its counsel,
accountants, and other experts for the accuracy and completeness
of the information submitted in connection with the ratings.
Standard & Poor's does not independently verify the truth or
accuracy of any such information.
This letter evidences our consent to the use of the
name of Standard & Poor's Ratings Services, a division of The
McGraw-Hill Companies, Inc. in connection with the rating
assigned to the units in the amendment referred to above.
However, this letter should not be construed as a consent by us,
within the meaning of Section 7 of the Securities Act of 1933, to
the use of the name of Standard & Poor's Ratings Services, a
division of The McGraw-Hill Companies, Inc. in connection with
the ratings assigned to the securities contained in the trust.
You are hereby authorized to file a copy of this letter with the
Securities and Exchange Commission.
Please be certain to send a copy of your final
prospectus as soon as it becomes available. Should we not
receive it within a reasonable time after the closing or should
it not conform to the representations made to us, we reserve the
right to withdraw the rating.
We are pleased to have had the opportunity to be of
service to you. If we can be of further help, please do not
hesitate to call upon us.
Sincerely,
