reconbob Posted October 10, 2018 Report Share Posted October 10, 2018 Posted by Bob for Doug: I thought some of you would be interested in seeing this photo. It is of the crate of stamping dies and other tooling we made to manufacture drum magazines. It is topped off with as many of the drum parts we made with the tooling that I could get into the crate. Sadly, the tooling is the only tooling made since WW2 that was made in accordance with the original drawings but no complete drum was ever made. To my knowledge, I am the only person who has all the original drawings to make the drums. I do not know what will happen to the crate. Right now I have it in storage. If any one wants to make real Thompson drums, call me, Doug Richardson, at 310-457-6400. Link to comment Share on other sites More sharing options...

Ron Mills Posted October 10, 2018 Report Share Posted October 10, 2018 Very impressive! I remember many years ago Doug put an ad somewhere looking for Thompson drums/parts "for destructive engineering purposes". Anybody else here recall that? Doug has always been one of our Thompson treasures. Link to comment Share on other sites More sharing options...
BillyDixon Posted October 13, 2018 Report Share Posted October 13, 2018 looking at photo all i see is top row of drum bodies,first draw, , how about photo of the tooling, you will need access to one heck of a big punch press.,just sayn Link to comment Share on other sites More sharing options...
MauserMatt Posted October 13, 2018 Report Share Posted October 13, 2018 What about a drum that fits the M1/M1A1? Link to comment Share on other sites More sharing options...
Ron Mills Posted October 13, 2018 Report Share Posted October 13, 2018 What about a drum that fits the M1/M1A1? Matt, that has been addressed on this forum; doing a Search should locate the thread. I'm thinking that either PK or Merle the Drum Doctor did that project. Link to comment Share on other sites More sharing options...

thirtyround Posted January 23, 2019 Report Share Posted January 23, 2019 Hypothetical question; say a party took on the manufacture of new drums... can that party use / stamp the drums "THOMPSON SUBMACHINE GUN" ?? or has that boat sailed? Link to comment Share on other sites More sharing options...
benedw60 Posted January 23, 2019 Report Share Posted January 23, 2019 The original auto ordnance is defunct so there is no that could sue you for using the name Link to comment Share on other sites More sharing options...
TD. Posted January 23, 2019 Report Share Posted January 23, 2019 Kahr Arms and/or Saeilo Enterprises, Inc. currently own the active trademarks for the names "THOMPSON" and "Auto-Ordnance." I doubt you could use those names on a product that is related to the Thompson submachine gun without some type of legal challenge from Kahr Arms. For example, note how the L drums from Taiwan no longer are stamped with the word "THOMPSON." Same with the new GPC C drums - no reference to the word "THOMPSON" is stamped on the product. Also note the "THOMPSON" name disclaimer in the GPC internet for sale listings for the C drums. Link to comment Share on other sites More sharing options...

reconbob Posted January 24, 2019 Author Report Share Posted January 24, 2019 (edited) The so called "Crosby" drums from Taiwan were an exact copy including the data plate thatsaid "Thompson". After they got out there Kahr caught up with them and that is why the wordThompson was removed from the plate.

TD. Posted January 24, 2019 Report Share Posted January 24, 2019 reconbob is spot on. The initial shipment of the Taiwan L drums with both the CROSBY and THOMPSON name stamped on the drums were a huge success. After Thompson enthusiasts realized these drums worked (and worked well thanks much to this Forum) it appears another shipment was placed. By then Kahr was ready. I don't know the details of what transpired, legal or threats of legal action, but I do know the result. The possessors of these new drums had to physically remove the Thompson name from the faceplate of the drum before it could be sold. Numrich Arms or Gun Parts Corporation (GPC) apparently had a lot of these L drums in stock because they were offering great prices on these drums (second variation?) while the inventory lasted. A search on the Board for Taiwan L drums will probably tell the story at the time and have pictures. A trademark owner does not have to license their mark. Period. It is their option whether to issue a license. Obviously, Kahr Arms did not issue permission or a license to use their trademark name, "THOMPSON," on these competing L drums. I don't believe the CROSBY Company gave permission to use their name but apparently they are so far removed from L drum production that they never protested.

thompsonteenager Posted January 24, 2019 Report Share Posted January 24, 2019 Yeah thats what i meant cause im trying to find out all the gun schematics so i dan build them for business when im older and good mags would be sweet Link to comment Share on other sites More sharing options...
thompsonteenager Posted January 24, 2019 Report Share Posted January 24, 2019 Also how would you even make the drum mags with the stamping molds? Like what machines material etc. Link to comment Share on other sites More sharing options...
Gio Posted January 24, 2019 Report Share Posted January 24, 2019 Thompsonteenager Im glad that you are very interested in the Thompson. You can learn a lot on this board however at your age I would suggest learning all you can about the Thompson by reading the suggested books. The making of parts requires a big budget as well as finding companies that can produce that particular piece. I wish you luck in pursuing this hobby. Welcome to the board.

ron_brock Posted January 24, 2019 Report Share Posted January 24, 2019 TT, Heres an example of production stamping. About 2:40 into this youll see some pans similar to a drum body. These start as sheet steel drawn into a cup in a progressive or deep draw press and die. I dont know what plans Doug had, but I assume lower volumes. Most of the drum components would be produced by stamping with a few staking and riveting operations. If the price of a transferable gun seems too much, forget about starting manufacturing on your own. Id suggest looking into careers in manufacturing (machining, tooling, engineering). Many of us gun nuts are also in likeminded careers due to the mechanical nature and interest in this kind of stuff. I learned a ton in college as I was in a cooperative program and spent a lot of time in the tool room with experienced machinists. Degrees are useless without practical knowledge.

Ron Indeed, I started my working life with an apprenticeship as a mechanical engineer and qualified as a tool fitter in a factory building locomotives. Unfortunately, in the UK heavy industry has about died a death, with all the old major industrial cities suffering from the loss, so those opportunities are not as freely available for our current school leavers, as they were back in the 1970's.

A mistake John T Thompson himself made in 1921, if you read the history, when AOC began their production of 15,000 Model of 1921's, many of which sat on the shelf for many years, some right up to WW2.
