One of the nice little things about this gun was it's name, the Liberator.
That was also the name of a single shot stamped metal pistol that was dropped by the thousands into occupied areas during WW2 for use by the resistance movements.
The allies dropped cases of them by parachute randomly across the countryside. They knew that most of them would be picked up by German troops or government units, but tptb would always wonder how many they had not found and had gotten into the hands of the resistance.
My FIL was with the 1st Division during WW2 and claimed they found many resistance units using the liberator pistols as they swept through Europe. Usually the pistol was backup for the weapon they had taken from a dead German they had killed with the liberator.
