This early Colt Model 1851 Navy was manufactured in 1851 as a third model with the small round trigger guard. It has an added/modified dovetailed German silver blade front sight, "-ADDRESS SAML COLT NEW-YORK CITY-" on top of the barrel, the small "COLTS/PATENT" marking on the frame, the standard Naval Battle of Campeche roll scene on the cylinder, and all matching visible serial numbers on the loading lever, wedge, cylinder, barrel, frame, trigger guard, and back strap.

Good with strong traces of original dull blue finish with a file mark showing on the bottom of the barrel and blue visible on the left around the wedge with smooth gray patina on the balance of the iron, modified front sight, 20% original silver plating concentrated mostly around the trigger guard with bright golden patina on the exposed brass, some scattered patches of light pitting, and a defined cylinder scene and markings. Grip is fine with some scattered light scratches, and some minor outer finish wear on the otherwise defined bottom edges. Mechanically fine.
