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 twenty being the rarest length. 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 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 hard rubber buttplate with S&W monogram. The original hard leather 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). Comes with a stock tang peep sight.

Fine. The revolving rifle retains 60% original blue finish with a smooth gray patina on the balance. Some minor pitting is present with some deep pitting on the back strap. The hammer and trigger guard some traces of original case colors otherwise faded to a silver-gray. The forearm and grips are excellent with limited minor handling marks and overall crisp checkering. Action needs work as hammer does not hold at the half cock position. The stock is very fine with 90% of the original blue remaining on the stock hardware and some minor handling marks on the wood. The case is fair with water damage on a short side overall wear.
