This Fourth Model 1851 Navy Revolver was manufactured by Colt in 1861 for the civilian/commercial market and has a dovetailed blade front sight, standard hammer groove rear sight, the one-line New York barrel address, standard "COLTS/PATENT" marking and cylinder scene, and matching serial numbers which generally also have the " ' " mark used by the factory to designate special features such as the grip on this revolver which is correctly hand numbered in the back strap mortise with the matching partial serial number. The open toe leather flap holster has no visible markings and appears to have original been finished black. Many of the Civil War era commercial handguns were purchased as private sidearms by soldiers.

Very good plus with 20% original blue which is mainly concentrated on the barrel, patches of vibrant original case colors on the rear of the loading lever, the majority of the original silver plating remains in the protected areas concealed by the grip, patches of original silver on and around the trigger guard, aged patina on the exposed brass, mild oxidation and brown patina on the balance of the steel, and mild overall wear. The grip is very fine and has attractive natural tones and grain, some minor age cracks (stable), and light handling and storage wear. Mechanically excellent. The holster is fair with absent stud, some tears at the flap fold, heavy flaking and rub wear, solid stitching, and pliant leather. This revolver and holster certainly have the look of having seen some serious use back in the 19th century but also having been cared for.
