Approximately 950 of Samuel Colt's Model 1839 Revolving Carbines were manufactured at the Patent Arms Manufacturing Co.'s Paterson, New Jersey, factory circa 1838-1841. They were the most successful of the Paterson firearms and were used by both the Republic of Texas and the U.S. Army. This carbine has a smoothbore part-round/part-beveled barrel with brazed lug. The lug is not fitted with a loading lever and has a flat, two-groove wedge and second transverse slot behind the wedge slot, a post front sight, and a dovetail mounted block rear sight. The right side of the barrel lug is roll-stamped "Patent-Arms M'g. Co. Paterson, NJ.-Colt's Pt.*" with wavy lines at the ends. The round-back cylinder is 2 1/2 inches long, was roll-engraved, and retains visible patent and address markings. The serial number "487" is found on the back of the barrel lug, wedge, arbor pin, turning ring, and toe of the buttplate, and "382" is on the back of the cylinder indicating the cylinder was replaced.
