A total of 30,362 Smith carbines were purchased by the U.S. during the Civil War. Smith carbines utilized gas sealing rubber cartridges and were considered to be accurate and reliable weapons by many of the cavalrymen they were issued to, but the unique rubber cases are also what caused them to be removed from service after the early years of the war. This example has the three sets of Massachusetts Arms, Smith patent, and Poultney & Trimble markings on the left side of the frame. The serial number is only visible on the barrel portion of the hinge. It features a blade front sight and a combination notch and folding ladder rear sight without range markings. There is a cartouche on the left wrist. This relatively early example has sling swivels on the barrel band and bottom of the stock instead of the cavalry saddle ring found on most examples.

Poor as partially refinished. The front section, hammer, and buttplate have a brown patina. The frame and trigger guard have a mix of brown and gray patina, and the rear collar and side plate have refreshed fire blue finish. The brass components have a dark aged patina. The wood is good and has several small strike marks and various light scratches. It is mechanically fine and has mostly crisp markings.
