This model was the first of .32-caliber rimfire Short revolvers that S&W produced. It is a larger version of Model 1, but is physically similar in appearance. Model 1-1/2 was offered with 3.5" octagonal barrel. Has a 5-shot non-fluted cylinder and square butt with rosewood grips. In 1866, a 4" barrel version was produced for a short time. Estimated about 200 were sold. Finish blued or nickel-plated. Serial numbering, on this model, ran from 1 to 26300; interestingly to note, S&W had most of the parts for this revolver manufactured on contract by King & Smith of Middletown, Connecticut. Smith & Wesson merely assembled and finished them. They were produced between 1865 and 1868. Note: Add 50% premium for 4" barrel variation.
