Re: National Municipal Trust Series 189
CIK No. 0001021740
Request for Withdrawal of Amendment to
Registration Statement on Form S-6
File No. 333-13257
Dear Sirs:
As Sponsor of the above-captioned Trust, we are
requesting a withdrawal of the four following submissions
pursuant to Rule 477(a) under the Securities Act of 1933, due to
an equipment malfunction. The four 485BPOS submissions that were
filed on October 22, 1998 under the accession numbers 0000898733-
98-000706, 0000898733-98-000707, 0000898733-98-000708 and
0000898733-98-000709 were filed in error. Although the EDGAR
access codes contained in the submission header for each of such
four filings were for Series 189, the underlying post effective
amendments were for Series of National Municipal Trust other than
Series 189. The information contained in the submission header
for each of the four filings was incorrect. We understand that
the four incorrect submissions will have no impact on future
filings.
If you have any questions, please do not hesitate to
telephone Philip Heimowitz of the law firm of Cahill Gordon &
Reindel, 80 Pine Street, New York, New York, collect any time at
(212) 701-3484.
Yours very truly,
