Lot 038 – 1921 Thompson Submachine Gun Trigger Spring

Original 1921 Thompson Submachine Gun Trigger Spring in very good used condition. The only difference I have seen in comparison of the Colt era Springs and the later WW2 springs with the springs which sit inside a recess, is the Colt Springs tend to have a more pronounced “tail” end sticking out which tends to hold the spring in the recess tighter then the WW2 springs. This may be only the way the spring comes off the machine that makes them and there is really no difference but all the springs came with Colt Parts years ago and were stored labeled as such.
