Liberator
Here's a rather rare handgun that was created during WWII. This is a FP-45 "Liberator" that was manufactured by the Guide Lamp Division of General Motors. It is a single-shot, smooth bore pistol that is chambered for the .45 ACP.
It was intended to be dropped behind enemy lines to help arm the resistance fighters.
Strictly a short range weapon, it was supposed to be used to take out an enemy soldier so that you could acquire his gun.
Many thanks to "JACKTHEDOG" for the nice pictures.
