M1928A1 Thompson 1945 "Longitudinal Section" Ordnance Drawing for sale

[reconbob]

      This is a quality copy of U.S. Ordnance drawing "Thompson Submachine Gun, Cal. .45  M1928A1 Longitudinal Section". The original date of the drawing is December 31, 1941 with the latest update dated April 20, 1945. Full size 24" x 40". I found this in Doug's (Richardson) files. The drawing is of interest because there are no measurements or dimensions on the drawing. it is a cutaway view of a complete assembled M1928A1 Thompson, with every part indicated by an arrow with a leader going to the name and Ordnance drawing number of the part. Also of interest is that the M1928A1 Thompson depicted has a finned barrel, but an M1A1 rear sight with the triangular guards. The 28A1 Thompson was no longer in production in April of 1945 so who knows what they were thinking. This is a rare drawing because it has no drawing number and so does not show up in any searches of the archives. They moved most of the U.S. Ordnance technical archives to Picatinny Arsenal, and I know that not everything made it there. (For example - the drawing for the M1A1 Thompson bolt.) You can get drawings from the Data Release Officer under the Freedom of Information Act, but they search by drawing number, not name. My guess is back in the day Doug had his sources and was able to get this before it was lost during the move to Picatinny.

     I am selling fresh, new prints/copies of this drawing for $25. It gets shipped rolled up in a tube, not folded. Postage is $12.50. If you live in New Jersey it may be $1 less, if you live in California, it may be $1 more, but $12.50 for all. You can send check of money order made out to Robert Bower, and mail to: Phila Ordnance, 222 Roesch Ave, Oreland, PA 19075.

Thanks
