Received a pistol from a relative it says Iver Johnsons Arms and Cycle Works on the barrel. removed the grip and it has 2 sets of numbers- on the side it says U29145 it then wraps the bottom with 995. The # 2 9761 is on the bottom under the trigger guard. it seems to have a safety trigger. 5 shot with a removable barrel. its has been well used. Any ideas on this gun? From reading and looking at other guns on this site mine is also hammerless and a single leaf.
