This is a very fine Civilian production, single shot, Model 1865 Navy Rolling Block Pistol, that was manufactured by the Remington, between 1866 and 1870. It has the distinctive spur trigger which identifies it as the first of the Remington Rolling Block pistols. The pistol has a blued barrel, color casehardened frame and fancy, highly figured walnut forearm and one-piece grip. The left side of the frame is roll-stamped with the two-line legend: "REMINGTONS ILION N.Y. U.S.A./PAT. MAY 3rd NOV. 15th 1864 APRIL 17th 1866". The top of the barrel is stamped with an anchor inspection mark. The pistol lacks the Naval inspector's markings on the right side of the frame, which are found on the U.S. Navy contract Model 1865 pistols. The pistol is in the original rimfire configuration and the breechblock retains the original rimfire firing pin. The Model 1865 Pistol was the first of the Remington Rolling Block Pistols. Original civilian production, rimfire examples are scarce; most Model 1865 pistols were apparently altered by the factory to Model 1867 configuration with trigger guard and were fitted with centerfire breechblocks.
