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. The 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. These firearms were serial numbered from 1 to 977 and out of the 977 manufactured, 514 had the 18 inch barrel. This example was also nickel plated which was even rarer than the barrel length with around 85-90 of the 977 featuring this finish instead of the standard blue. It will factory letter as shipped on May 10, 1892, and delivered to Hartley & Graham of New York City, the type of finish was not noted in the shipping record. The 18 inch barrel features a blade front sight, two leaf "V" notch rear sight, and two-line address/patent dates legend. Matching serial numbers appear on the butt, cylinder, barrel latch, and barrel. 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 New Model No. 3 tang-style stock is smooth walnut with nickel finished attaching iron and a checkered black hard rubber buttplate with S&W monogram. It is not tapped for a tang sight.

Excellent, retaining 95% plus of the untouched original nickel finish with some scattered very light flaking. Traces of original case colors remain on the trigger guard. Hammer retains 90% original case colors. The forearm and grips are excellent with a few handling marks and overall crisp checkering. The stock is excellent, retaining 98% plus of the original nickel finish, a filled chip on the buttplate toe, and a few handling marks. Mechanically excellent.
