Manufactured circa 1873 to 1878 this model is commonly known as the Old Model Russian and is easily recognizable by the spurred trigger guard. The Second Model Russian was also manufactured with a 7 inch solid rib barrel and features a pinned blade front sight and notch rear sight on the barrel latch. The serial number is stamped on the butt along with "SH" inside a diamond. The "SH" inside the diamond indicates this is a fairly scarce variation of the Second Model Russian which would have been purchased and subsequently marked by Schuyler Hartley & Graham. The matching assembly number "00" is stamped on the rear face of the cylinder, barrel, barrel latch and on the left side of the grip frame. The top of the barrel rib is marked "SMITH & WESSON SPRINGFIELD. MASS. U.S.A. PAT. JULY 10.60. JAN. 17. FEB. 17. JULY. 11 65 & AUG. 24. 69." flanked by Maltese crosses. All blue finish with casehardened hammer and trigger guard.
