Inland Guide Lamp Mfg. Liberator .45 ACP caliber pistol. Scarce Liberator .45 caliber single shot. These were air dropped to the Philippines in WWII with a box, 5 cartridges and instructions sheet. The idea was to use the pistol to kill an enemy solider (the Japanese) then take his gun which was a much better weapon. These are made out of sheet metal and riveted together. These are very collectable WWII guns.
