Bridgeport28A1

The punch inside the loop of the P at top center is the proof firing punch. The punch in that location is consistent with Savage production.

It looks like a nice Savage plain barrel that is indexed and has a firing proof punch. I am assuming your Thompson has a plain L rear sight.

The officer on the left side of the hood getting the Thompson pointed at him and the officer top left appear to have Reising’s in their hands. Photo dates to at least 1942 and likely later.

For what it is worth, I cleaned one at the MN Military Museum years ago. A wife of a Korean war veteran had donated it to the museum. It had been in the house attic prior to the donation and the story was it was brought back to the US from Korea by the veteran . The was a torn square piece of fabric in the buttstock compartment. I did not write an information down as a quite a few submachine guns and other military firearms were cleaned. I expect it is likely a Form 10 registered gun at this point.

To start the serial number change over to pinned threaded boss. My Savage M1 frame has 2861?0 stamped on the trigger guard. I have not been able to determine what the fifth digit is.

I like the Ogden marked stock.

TD. I will dig it back out tomorrow and post a photo of the top of the frame. It is not very pretty M1 frame but it is mine. In my experience I found the M1 frames to be harder to locate than 1928A1 frames. I believe Taliaferro has a low number M1 on display. I am curious if there are any other very low serial number frames that are numbered like this threads #5901 example in Europe? Maybe Taliaferro would let you take a peak under the buttstock in August to see if there is a number?

Jim, the padded jump case is an excellent suggestion. Better solution then the leather BAR scabbard.

TD, not all Savage M1 frames had a pinned threaded boss. Some Savage frames had a machined threaded boss. The FULL AUTO marking on two lines and the George E Goll GeG stamp are the two best ID methods.

You could go old school. Not padded but original WW2. https://www.ebay.com/itm/295708418751?chn=ps

No felt in the breech oiler on the visible portion.

Bob, an excellent write up on determining the value of Thompson parts in 2024.

I believe Balder is in Norway and not in the US.

This thread is going to have me looking at my spare sears and sear levers. The odds of me ever needing any of my trigger frame parts is likely near zero. But they are not making them anymore.

I have a couple of questions regarding trusts. Asking for a friend...LOL I know these are lawyer type questions but thought a member may already know the answers. Is a NFA item that is held in a trust allowed to be transferred to an heir on a Form 5 after the trust maker dies? This is assuming there are no successor trustees. Trusts that I have read become irrevocable when the trust maker dies. What happens to the NFA item when the remaining trustees die and there is no one living named in the trust.
