I need an early production 1897 Winchester pump 12 gauge. It needs to be manufactured before June of 1898. Will probably have a serial number less than 80000. It must have the threaded barrel that screws into a solid frame, not the take-down model. This is the way they were built up till June of 1898. Gun can be a P.O.S. as long as the barrel is at least usable. The longer the barrel the better, I'm not looking for a trench gun. Prefer P.O.S. in order to keep the cost down.
