Manufactured from 1879 to 1887, the Model 320 revolving rifle is one of the rarest Smith & Wesson firearms manufactured produced with a total production of 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, only 224 were manufactured by Smith & Wesson. The 20 inch barrel has a blade front sight and two leaf folding rear 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. Blue finish with casehardened trigger guard and hammer. 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.

Fine. The revolving rifle retains 50% plus original blue finish with the balance a smooth brown patina. Traces of original case colors remain on the hammer and trigger guard. The forearm and grips are some minor handling marks (mostly on the bottoms of the grips) with overall crisp checkering. Mechanically fine. The stock is very good with the refinished attaching iron retains 97% of the blue finish, and the wood has a hairline crack near the upper tang and a number of minor handling marks with a worn buttplate.
