Thanks for the advice. I doubt it was ever used in a crime, he was from Pennsylvania Dutch stock. It was likely acquired in his youth or maybe when he was in the Army, probably purchased for sport more than anything else.
by the way, if it is old, the ammo, and especially the box if you have it may be worth more than the gun. Guys at gun shows lately have been goin gaga over old ammo boxes for some reason.........
