Hello everybody I'm new here and immediately have a question about Thompson. It's about a 1927A1 from Auto-Ordnance from the 80th years. Unfortunately, I do not know the structure so well. What I noticed, however, was that a closure as in the M1A1 (with a firing pin) was installed. The loading lever is, however, like the 1928 above. As for me, the question arises, whether that was so officially made at the 1927A1, or if it is a low budget version? Furthermore, I would be interested in whether the 1927A1 frame corresponds to the 1928A1 or the M1A1? Many thanks for your help. Greeting Johny
