Son-Of-A-Gun-- picked up a hammer twist barrel 16 ga. aprox-- percussion cap muzzle loading single barrel- payment from a farmer friend for a welding job-- Just happened to be looking through a friend's copy of the Ed Muderlak book "Parker Guns- The Old reliable" and on page 235- a dead-nuts print with dims of the Nov 24 1868 J. Stokes Pat'd gun lock- exactly as the one I removed from this older single barrel- cleaned up the rust and grime- all parts are there, and it works- ain't America great!!
