The Model No. 3 , a.k.a. The American .44 Model, really put S&W into the game ! Prior to 1870, the company’s only “big frame” revolver was the less than big frame Army No. 2 in .32 rim fire. However in 1870 they geared up and introduced the top break, .44 Models, the American Model in .44 AM, and the Old Old Russian Model in .44R, physically the same except for caliber. QUICKLY followed by the 2nd Model, which made a slight change in the frame, to accommodate the stronger trigger hold pin. This 2nd American, Serial No. 2175X, is in remarkable condition. It has about 95% of all the original nickel plated finish. What is IMPORTANT, it has never been touched ! no cleaning, polishing etc… it has that natural 141 year old luster. ALL assembly numbers are matching, all serial numbers match, and ALL parts are original. Mechanically it operates PERFECTLY, breaking open, closing, cocking, locking and firing , every time ! ALL factory applied markings are present and visible.
