This Civilian Colt Model 1860 Army revolver was manufactured in 1866. The revolver has a civilian style, three screw frame with no stock cut-outs in the recoil shield and rarely encountered blued, steel trigger guard. The revolver has grips with a highly detailed, relief carved Mexican Eagle and Rattlesnake motif in an oval on the left side. The barrel, cylinder, trigger guard and back strap have a deluxe, high polish blue finish. The loading lever, hammer and frame are color casehardened. The cylinder is roll-engraved with the Texas Navy battle scene and "COLT'S PATENT. The top of the barrel is roll-stamped with the legend "-ADDRESS COL. SAML COLT NEW-YORK U.S. AMERICA-" in a single line. "COLTS/PATENT" is stamped in two lines on the left side of the frame. "44 CAL" is stamped on the left shoulder of the trigger guard. The full serial number is stamped on the bottom of the barrel lug, frame, trigger guard and back strap. The partial serial number, "8197" is stamped on the cylinder. The "8" is struck over a number "1", a factory error. There is an "L" suffix stamped on the frame and trigger guard under the serial number. All of the serial numbers match.
