Manufactured from 1879 to 1887, the Model 320 revolving rifle is one of the rarest Smith & Wesson firearms manufactured 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.

Very fine as factory refinished. The revolving rifle retains 98% of the blue finish showing some mild thinning on the cylinder. Minor pitting is present on the frame under the grips. The hammer and trigger guard most of the case colors. The forearm and grips are excellent with very limited minor handing marks with overall crisp checkering. Action needs adjustment. The stock is fine with 40% of the blue finish remaining on the attaching iron and a few minor handling marks on the wood.
