Manufactured from 1879 to 1887, the Model 320 revolving rifle is one of the rarest Smith & Wesson firearms produced with a total production of 977. These firearms were serial numbered from 1 to 977, and out of the 977 manufactured, 514 had the 18 inch barrels. Only 840 of these were sold in the U.S., and the remaining 137 were exported. This scarce and unusual revolving rifle was sometimes referred to as the Smith & Wesson "Buntline Special" in the combination of a long barreled revolver with attaching shoulder stock. This Model 320 was manufactured using the frame, cylinder and basic action of the New Model No. 3 revolver with some minor differences in the hammer and trigger, with the barrel being made of two pieces. A slot is cut into the butt and a hole drilled in the back strap to accommodate the shoulder stock. The rifle features an 18 inch barrel with a blade front sight and two leaf folding rear sight. The top of the rib is marked with the two line address/patent dates. The matching two digit serial number appears on the butt, cylinder and barrel latch. Blue finish with casehardened hammer and trigger guard. The barrel is fitted with a checkered hard rubber red mottled forearm with the S&W monogram on the underside. The grips are matching with S&W monograms in a circle at the tops. The stock is smooth walnut with blue finished attaching iron and a checkered black hard rubber buttplate with S&W monogram. The original hard leather case has brass corner protectors, felt lining and three compartments (one for the rifle, one for the stock and one for a box of cartridges). Comes with a stock tang peep sight.

Fine. This revolving rifle retains 50% original blue finish with a smooth brown finish on the balance. Some minor pitting is present on the cylinder. The hammer and trigger guard retain some vivid original case colors. The forearm and grips are both very fine with very limited minor handling marks and overall crisp checkering. The stock is also fine with traces of original blue finish on the attaching iron and some minor pressure dents and scratches overall. Mechanically fine. The case is fair with the lid mostly detached, worn lining and missing straps.
