j stevens arms and tool company is the name on this shotgun. old single shot. the pistol says; Mass.Arms.Co. Chicopee Falls.Mass. choke bored its in old condition, and cant make out everything on it. has some engraving along the left side above trigger, too worn to see what it says. so im just lookin for information on these guns. both came from my granparents, who got them from their parents. and now i found/have them. i dont plan to ever get rid of them, but i do wanna know as much about them as possible. should i try and clean them up? or let them be? thanks.
