Manufactured from 1866 to 1875, this pistol is essentially the civilian version of the Navy Model of 1865/1866, making it very rare. It is estimated by Jerry Landskrom in "Remington Rolling Block Pistols" that less than 500 of these commercial versions of the Navy pistols were made. The top of the barrel is marked with the Navy anchor and "REMINGTON'S ILION.N.Y. PATd OCT.1.1861 NOV.15.1861" but bears no other inspection marks, typical of the commercial models. The front sight is the standard fixed pinched style, and a notch in the top of the breech block serves as the rear sight. The barrel is blue, the hammer a nitre blue, and the remaining metal is casehardened. Fitted with a smooth walnut forearm and one-piece grip that is numbered "4" inside.
