I have recently inherited a 12 ga. single barrel shotgun that was my great grandpa's gun. I got it after my grandpa past away. I don't really know anything about it other then my grandpa hunted with it in the early 1900's and his dad hunted with it before that. The only distingusing things that I can tell you are that it doesn't have a name on it that I can find. The top of the barrel is steel stamped with "ROLLED STEEL". There is a horse standing on it's hind legs on the butt of the gun. There is a number stamped on the side of the barrel that can only be seen when the barrel in broken down and the number is "3347". The lever to break the gun down is a top lever. There is a lever on the side of the gun, near the trigger, that you have to use to "cock" the internal firing pin. There are no external hammers. There is also a cover on the side of the gun opposite the cocking mechinizm that looks as though it would give you access to the cocking mechinizm and the working internals of the trigger. I am just trying to find out some info on this old family gun and would appriciate any help that you may have.
