Remington's revolvers were the second most widely issued by the Union throughout the Civil War, and the New Model Army revolvers became the primary issue revolvers of the Union cavalry after the fire at the Colt Armory on February 4, 1864. Manufactured from 1863 to 1875, these represented the last of Remington's .44 caliber percussion revolvers. The barrel, trigger guard finial, and left side of the grip frame have the matching serial number, and the left grip appears to be numbered to the gun in pencil. Single letter sub-inspection marks are located on various components. A boxed script "BH" (Benjamin Hannis) inspection cartouche is stamped on the left grip panel. Features a "pinched" blade front sight and top strap groove rear sight.
