GREAT to hear.

Here is a relevant thread. Specifically, look at reconbob's comments. I would strongly suggest speaking directly with a Thompson gunsmith before attempting anything, lest more issues be created. PK, reconbob or deerslayer come to mind. If the consensus recommendation, for YOUR issue, is the same as suggested for the one in the linked thread, it would be best to have a pivot plate tool, borrow or make one.

Attempted to correct the color as a Moderator, no joy, above my pay grade, I was able to post this clean version for you. As to your question: "Realizing that, at some point, the gun will be sold, I would greatly appreciate some input re: which of the following would be considered the most desirable when that time comes: My response would be your top choice, it should be the most desirable, for a resale. "1921/28 "Navy Overstamp" Your 2nd choice, Bridgeport, Connecticut 1928A1, would still give options to shoot drums, be a more affordable choice compared to the Navy, still be a good resale choice and have much reduced concerns to shoot potentially causing damage to very expensive and hard to find parts for the above Navy. The Navy could and can be shot by replacing the upper internals with Military parts, but you still have the original barrel which if damaged from say a squib / bulge would be devastating to find a replacement to match and it will never match again if that happens.

ATF letter on Estate possessed NFA firearms

I found "Leg Vises" as the reference for the Patent, no other details found yet. Certainly not for a Thompson submachine gun when the patents were late 1800's. http://vintagemachinery.org/mfgindex/detail.aspx?id=12322&tab=7

Barrel has no witness mark. No picture of an Anchor stamp on the rear stock has me suspicious. Both Front Rear grip do not appear correct to me but that is just me. These items are always better purchased after a direct visual inspection. No Witness mark and some mark is clocked above where one should be but not a witness mark Rear grip has an unusual appearance, should be a crisper line coming back from the trigger guard An example of a rear grip with a crisp line coming back from the trigger guard Front grip has an unusual shape F Another front grip to compare

Money WELL spent to do it correctly. Totally agree with Tom. While there might be available barrel changing tools, when installing another barrel, to get the compensator to correctly line up, almost assuredly will require a machine shop, preferably one with experience. A different barrel with an already pinned on compensator, more likely will not line up perfectly, thus the need to remove the pin, line up the compensator, drill and pin it in the correct lined up position.

Bob David Madlinger is what my contact list has for the owner of this website / Thompson parts maker, it's been a while, not sure if he is still in business. If you read the linked page, you should find he mentions availability of a Type 2 compensator. Good luck https://thompsonbarrels.com

The Thompsons and the drum were never shipped as a matching set of numbers.
