Manufactured in 1870. The top of the barrel is marked "-ADDRESS COL. SAML. COLT NEW-YORK U.S. AMERICA-" and "COLTS/PATENT" is on the left side of the frame. The cylinder is roll engraved with the Texas naval battle scene and marked "ENGAGED 16 MAY 1843" on the front edge and "COLTS PATENT No 646". The complete matching serial number is marked on the bottom of the barrel lug, frame, trigger guard and back strap, and the cylinder and cylinder pin are marked with the partial serial number "646". The wedge is un-numbered. The barrel, cylinder and back strap have the Colt high polish blue finish. The loading lever, frame and hammer are color casehardened and the brass trigger guard is silver-plated. Blade front and hammer notch rear sights, and fitted with a smooth one-piece walnut grip.

Very fine as factory quality period refinished. The revolver retains 60% of the factory quality blue finish with loss due to flaking. The majority of the remaining blue finish is bright and shows minimal wear. The loading lever, frame and hammer retain 95% of the original vivid case colors. The trigger guard shows traces of the original silver finish with a very attractive untouched aged patina on the brass. The cylinder retains 95% of the scene. The markings are crisp and clear. All of the cylinder pins are intact and the action is excellent. The grip is very fine with traces of the original varnish in protected areas, some very minor lower edge wear and light handling marks. This is an attractive example of a post-Civil War Colt Model 1860 Army revolver.
