I just acquired a WWI P38 from my wife's uncle. He is 98, and says he took it from a battlefield in mid 1945. It was in his closet for about 20 years and his safe since then. He has never shot it or showed it to anyone until he gave it to me last week. He never talks about the war and did not give me any more info. It has P38 9027a ac 45 on the slide, and 9027A on the frame. From the attached pictures, can someone give me some additional info on the gun?It looks almost new, and the riffling looks like it could not have been fired much if any.
