This is a replica of a French military pistol that was copied by Simeon North for use by the U.S. military. I have stamped U.S. on the side plate to represent this type. I converted it from its original flintlock to use percussion caps. This makes it a much better and more reliable handgun. It is .69 caliber or 14-gauge smooth bore. I have loaded it with a round ball or shot. $450.00 + shipping.
