This rare early Colt rifle was manufactured by the Patent Arms Manufacturing Co. in Paterson, New Jersey, c. 1837-1838 and is one of the very first firearms manufactured by Samuel Colt. These First Model rifles actually pre-date Colt's first factory produced revolving handguns by a few months. The "Improvement in Fire-Arms" for Colt's "Revolving Gun" were patented in the U.S. on February 25, 1836, and included design aspects used in many of Colt's subsequent firearms designs such as the barrel secured to the frame via the cylinder arbor and wedge. 1/4 of the 200 manufactured were ordered by the U.S. military for the army during the Second Seminole War. Given how early these revolving rifles are and how few were made, they are the rarest Colt Paterson, and any surviving example is highly desirable. They were followed by the Paterson handguns, Second Model Ring Lever rifles, and the Model 1839 revolving long guns. Though Colt's Patent Arms Manufacturing Co. ultimately failed, it set the groundwork for his later immense success. The ring lever on the bottom of the frame cocks the internal hammer and rotates the cylinder. The barrel has seven-groove rifling, a dovetailed nickel-silver blade front sight, dovetailed rear sight with screw adjustable notch, "-Colt's Patent-Patent Arms Man'g. Co., Paterson, N. Jersey.-" roll-stamped on top of the breech section, and small loading grooves on the left and right at the breech. The squareback cylinder has knurling, a "COLT" markings, and the deer, centaur, and horsemen scene. The frame has a top strap with a small, square cut-out at the rear and a smaller, semi-circular cut-out at the junction with the barrel. The frame is not cut for capping. Matching serial numbers are located on the back of the barrel lug, wedge, back of the cylinder, arbor pin collar, and toe of the buttplate. The nicely figured buttstock has the endorsed "C" four horse head emblem inlaid on the very nicely shaped cheekpiece and a narrow crescent buttplate.
