Manufactured 1879 to 1887 with a total production of only 977, this is one of the rarest Smith & Wesson firearms produced. Of the 977 manufactured, only 239 were made with the 16 inch barrel and only approximately 85-90 featured nickel plating, which is less than 10% of all production. This scarce and unusual revolving rifle 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 composed of two pieces. A slot is cut into the butt and a hole drilled in the back strap to accommodate the shoulder stock. The 16 inch barrel features a globe front sight (insert absent), a two leaf folding rear sight and a solid rib stamped with the two-line address/patent dates marking. Matching serial numbers are on the butt, right grip panel, cylinder, barrel, and barrel latch. The forearm and grips are checkered mottled hard rubber featuring S&W monograms. The stock is smooth walnut with nickel attaching iron and a checkered hard rubber buttplate with S&W monogram.

Very fine, retaining 90% plus original nickel finish with light flaking throughout and heavier flaking on the grip straps. The hammer and trigger guard retain 85% original case colors. The forearm and grips are also very fine with a with a small chip near the bottom (left grip panel) and crisp checkering overall. Mechanically excellent. The stock is very fine with minor handling marks on the walnut and 95% original nickel on the attaching hardware. A highly prized, high condition Model 320 revolving rifle with rare original nickel plating. Provenance: Dr. Gerald Klaz collection.
