This mueseum quality sub-machine gun designed after the gun the "Made the 20's roar", is honestly the best Thompson I have ever seen! This is what I believe to be a Savage "Commercial" model. It is a model 1928. The receiver is marked Auto Ordnance New York, New York. It comes with a vintage 50 round drum, a newer 100 round drum. It has knarled selectors, Lyman sights, Cutts compensator and Colt internals. Manufactured in 1941, it went to an east coast police department from the factory.
