Note: Dating a Smith & Wesson revolver using generic lists is a general guide and not always exact. Your gun may actually be a year off from what is listed. The precise shipping date, as "lettered," can be several years off depending on the model.
For all S&W revolvers, the official serial number of record is stamped on the bottom of the grip frame. If the revolver has grips (stocks) that cover the bottom of the frame, they will need to be carefully removed to access the serial number. The only rare exceptions to this rule are a few small .22 and .32 caliber revolvers from the early 20th century, which have the serial number stamped on the front strap of the grip frame (the part facing the trigger guard).
