Was in China during WW11Was your father in Vietnam? There was a considerable trade in handmade copies of 1911s. Browning HiPowers,and other popular handguns throughout the Vietnam War. The "serial numbers" are gobbledygook. If of an earlier era, perhaps a Chicom hand made pistol from the Korean War era? In any event, definitely a curio rather than a shooter, and rather cool at that.
