Manufactured from 1879 to 1887, the Model 320 revolving rifle is one of the rarest Smith & Wesson firearms manufactured, with total production of only 977. These firearms were serialized from 1 to 977. The Model 320 was manufactured in three barrel lengths of 16, 18, and 20 inches with twenty being the rarest length with only 224 were manufactured by Smith & Wesson. The 20 inch barrel has an L shaped two blade rear sight and lacks a front sight. The top of the barrel rib is marked with the two-line address/patent dates. The matching serial number appears on the butt, cylinder, barrel and barrel latch. The barrel is fitted with a checkered hard rubber red mottled forearm with the Smith & Wesson monogram on the underside. The grips are matching with Smith & Wesson monograms in a circle at the tops. The stock is smooth walnut with blue finished attaching iron and a checkered hard rubber buttplate with Smith & Wesson monogram. A factory peep sight is mounted on the stock attaching hardware. Includes a soft case.

Good, displaying character associated with spending a lifetime in a challenging environment mixed with period refinished blue finish over light pitting. The grips and forearm are very fine as replacements with minimal handling marks and crisp checkering. Mechanically fine. The stock has hardware with similar refinished appearance and replacement wood with some scattered handling marks. The canvas case is fair.
