This revolver was manufactured in 1862 and has the "I" suffix stamped above/below the main serial numbers used to indicate special order grips like the one found on this revolver. The grip also has the matching partial serial number properly handwritten in black ink in the back strap mortise. It may have been ordered by or for a Union Army officer as the Model 1851 Navy was the standard sidearm of the period. It has a brass cone front sight, "-ADDRESS COL. SAML COLT NEW-YORK U.S. AMERICA-" along the top of the barrel, the standard Naval Battle of Campeche scene and patent markings, and all matching serial numbers.

Very fine overall. The revolver appears to have seen very little if any use and has all of the cylinder safety pins, 85% plus bright original high polish blue finish remains on the barrel, distinct battle scene and blend of gray and brown patina on the cylinder, 80% plus of the vibrant original case colors, traces of original silver plating on the grip frame which displays aged patina on the exposed brass, and minor marks and scratches. The excellent original grip has very attractive natural tones and grain, a minor age crack near the heel, and minor handling and storage marks. Mechanically excellent.
