Large pistol at over 15″ long. Cal about 69. Smooth bore. There is no markings on the gun. Bbl is mostly rusted with a grey/rust patina. Inside is somewhat rusty also. Brass hardware on the rest of the gun. There is a screw missing on the bottom of the butt plate. There is also a ring on the butt plate but don’t know if that was orig or put on later. Frizzen pan has a good spring as does the hammer. Hammer does not cock all the way back however. There are numerous cracks and slivers missing. Even has some worm holes. What a great piece for display or conversation.
