Offered here is an exceptional example of a first year production Colt Model 1851 bearing serial number 537 that was manufactured in 1850, featuring the distinctive squareback trigger guard and wedge over screw. This is one of only approximately 800 Model 1851 Navy revolvers manufactured with the barrel wedge positioned over the screw that distinguishes them as First Models. The Colt "Revolving Belt Pistol of Naval Caliber" was designed between 1847 and 1850 and was initially called the Ranger Model, with 215,348 reportedly manufactured between 1850-1873. This early production example has the early style barrel with a non-beveled loading cut out, retaining screw located under the wedge, brass cone front sight, and "-ADDRESS SAML COLT NEW-YORK CITY-" stamped on top. The left side of the frame has the "COLT'S/PATENT" marking. The cylinder has the classic Naval Battle of Campeche roll scene. The trigger guard has the early squareback bow. Matching visible serial numbers marked on the loading lever, barrel, wedge, cylinder pin, cylinder, frame, trigger guard, butt, and correctly handwritten in black ink inside the back channel of the grip. Provenance: The Andrew Singer Collection

Fine with a very fresh original appearance, retains 40% original blue finish, strong patterns of original case colors showing vivid in some of the protected areas, scattered characteristic freckling and brown and gray patina on the balance, a few small patches of minor pitting, 90% original silver finish on the trigger guard and grip straps with an attractive slightly tarnished original appearance, with a crisp cylinder scene and markings overall. Grip is very fine with most of the original varnish finish with some minor surface flaking around the lower edges, some scattered light scratches and dents, a small minor chip in the lower front left corner, defined edges and tight fitment. Mechanically excellent. This exceptional First Model Colt '51 Navy would greatly enhance any comprehensive Colt firearms collection!
