Deactivated EU/UK Spec Thompson M1A1 SMG in very good deactivated condition, with moving cocking handle, safety, fire selector and removable magazine. The M1A1 was the war production variant of the 1928 model Thompson. The Blish lock was done away with and a heavier bolt utilized to slow the rate of fire. The cocking handle was moved to the side and the compensator was done away with. A simpler battle sight was added and the barrel fins were done away with. Also, the stock was permanently attached. These changes made the weapon more reliable and less prone to jamming and also took about a pound in weight off the gun. A great piece of US military history and used by the US and her allies well into the Vietnam war. All deactivated weapons sold by D and B Militaria are deactivated in the United Kingdom and hold a London or Birmingham proof mark and certificate stating that the weapon has been deactivated correctly and is legal within the U.K.
