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 serialized from 1 to 977 and out of the 977 manufactured, 224 had the 20 inch barrel. The Model 320 was manufactured in three barrel lengths of 16, 18, and 20 inches with 20 being the rarest length. The 20 inch barrel has a globe front sight with cross hairs 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 S&W monogram on the underside. The grips are matching with S&W monograms in a circle at the tops. The stock is nicely figured walnut with blue finished attaching iron and a checkered hard rubber buttplate with S&W monogram. Equipped with the rare combination of special order rear peep and front globe sights. The incredibly rare original case has double leather straps, a leather handle and brass corner protectors. The lining is felt and there are three compartments (one for the rifle, one for the stock and one for a box of cartridges). Also comes with a cleaning rod, an original slide on blade front sight and rare stock tang filler screw.

Very fine. The revolving rifle retains 60% original blue finish with a smooth brown patina on the balance. The hammer and trigger guard retain 50% original case colors. The forearm and grips are excellent showing limited mild handling marks with overall crisp checkering. Mechanically fine. The stock is very fine with 70% original blue finish remaining on the attaching iron and a few minor handling marks. The case is fair with a replacement strap and some missing hardware.
