I inherited an old double hammer 12 ga. the only markings I can find ar L.C. Smith on both sides of the reciever and hunter arms Fulton NY on the rib. No numbers no guage or choke stamps. how can I find out any more about the history of thi gun. my dad got it from a cousin who would be about 98 if she were still living. This was her fathers shotgun. Much used and abused.
