This revolver was manufactured in 1863 and has single letter U.S. inspector markings on the barrel ("D"), cylinder ("D"), trigger guard ("H"), and back strap ("H"). The barrel has a German silver blade front sight and the one-line New York address. The cylinder has the classic Naval Battle of Campeche roll scene. The frame is cut for a shoulder stock and has "COLTS/PATENT" lightly struck on the left. Matching serial numbers are visible on the cylinder, barrel, frame, trigger guard, and back strap. The revolver was fitted with a pair of checkered grips with a raised relief carved rendition of the coat of arms of Mexico in raised relief on the left showing a golden eagle with a rattlesnake in its beak perched on a cactus. After the American Civil War, Mexico was a significant market for firearms as the country went through its own series of revolutions and civil wars. After the Civil War, the U.S. government sold of thousands of surplus arms, some to Mexican officials.

Very fine with mostly silver-gray patina and a crisp scene on the cylinder, attractive aged patina on the brass trigger guard, 75% plus original blue and casehardened finish on the remainder, and mild dings and scratches. The undersized period replacement grip has crisp checkering and carving, minor age cracks, and attractive natural aged tones and grain. Mechanically excellent.
