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, 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. Only approximately 85-90 feature nickel finish. That is less than 10% of all production! The 20 inch barrel has a blade front sight and two leaf folding rear sight and is stamped with the two-line address/patent dates marking. Matching serial numbers are on the butt, cylinder, barrel and barrel latch. The forearm and grips are checkered red mottled hard rubber with S&W monogram. Comes with the correct and proper period case.

Fine, retaining 60% original nickel plating with the balance a mixture of smooth brown and gray patinas along with some cleaned pitting. Traces of original case colors remain on the hammer and trigger guard. The forearm and grips are very fine with a few scattered minor handling marks and crisp checkering overall. Mechanically excellent. The well worn and repaired case is poor with added interior straps. Provenance: Dr. Gerald Klaz collection.
