I know nothing about guns, so I could use a hand here. I’m going to purchase a WWII US Army jacket and Japanese flag from a man whose dad was in WWII in the Pacific and served at Biak in New Guinea. According to the man, his dad picked up the flag and a Colt .45 from a dead Japanese officer. He said the serial number on the .45 was filed off.
After the war, he brought the .45 to a gunsmith who was able to re-stamp the serial number back on the .45 so he could register it. The gunsmith also engraved the top of the pistol with his name, date of capture etc. I’m waiting for more pics to arrive of the other side of the pistol.
So my questions are the following: is this an official WWII era U.S. Army Colt .45; why would the Japanese have filed off the serial number; is the gold inlay original to the pistol or was it done post war by the gunsmith; is it worthwhile to purchase the pistol?
Any thought or suggestions would be greatly appreciated.
