I just inherited a pistol, where do I find out about it. On the slide it is stamped FaMARTIN A. BASCARAN-EIBAR. Under that it has a round button then the letters tian" CAL 765. on the upper part of the hand grip in back are the letters ZC or ZG in a circle. I found it in the bottom of an old dresser at my mother in laws home. She died and her husband died about 12 years ago. Her husband was in WWII but he was in the pacific. I would like to find out more about it and possibly how old it is. I took it to a gun smith to have it serviced but he could not tell me much about it either.
