I’m not really sure about what model the Tommy in European Assault was supposed to be. The cock handle is on the side, which is like the M1 or M1A1. However, the iron sights make it appear to be the M1928. The game calls it the M1, but I’m not really sure it’s accurate, especially since I know the Brits at St. Nazaire had M1928s.
I know in Frontline, you have the M1, and in Rising Sun, you have the M1928.
