This scarce factory engraved Colt Model 1851 Navy revolver was manufactured in 1851, the second year of production. The engraving consists of broad leaf scrollwork accented with border designs, cross hatching, and shell patterns. A patriotic motif is engraved on the recoil shield, a shield is engraved on the trigger guard, and a wolf head is engraved on the hammer. "COLT'S/PATENT" is engraved inside a flowing banner on the right side of the frame. This marking is commonly located on the left side of the frame. The cylinder has the roll engraved naval scene. The top of the barrel has the one-line New York City address accented with engraved embellishments. It has the standard features for the Second Model which has the wedge under the screw unlike the First Model and retains the squareback trigger guard of the First Model. Only approximately 3,000 of these revolvers are estimated to have been manufactured given the serial number range of 1250-4200 includes some of the early Third Model revolvers. Matching serial numbers are found on the frame, barrel, trigger guard, back strap, loading lever, wedge, and cylinder pin. A factory "*" reserved for special finishing and engraving is marked above or below most the main serial numbers. Fitted with a burled walnut grip. The partitioned case contains lead rounds, W&C Eley cap tin for Colt model arms, correct early pattern "COLTS/PATENT" marked brass bullet mold, "L" shaped combination tool and patriotic motif double face "COLTS/PATENT" marked powder flask.

Very good plus. Some areas of original blue finish remain on the protected areas of the barrel and some silvered out original case colors remain on the frame, otherwise the revolver has a smooth brown-gray patina. Nearly all of the cylinder scene remains. The engraving is crisp. The grip straps retain 80% original silver plating. The grip is fine with a hairline crack and numerous tiny dings on the bottom, otherwise some minor handling marks and retaining much of the original finish. Mechanically excellent. The case is very good with numerous handling/storage marks on the exterior and fading and wear on the lining. A rare early production Colt Squareback Model 1851 Navy Revolver with the added bonus of being factory engraved that will make a great addition to any antique Colt collection.
