Let me get this straight. You found a pistol made by the Iver Johnson Gun and Bicycle company in the woods and picked it up off the ground.
hmmmmm. Did you try to rub it and see if a genie would come out?
Couldn't resist. You should get an answer in the morning from a fellow gent here. Check back. If you don't get one in a couple of days then try to start a new thread and call it Iver Johnson question. A pic or two will also help him if possible.
