Manufactured from 1891 to 1911 with a total production of 26,850. The top of the barrel rib is marked with the two line address/patent dates with "MODEL OF 91" in the center. The matching serial number is marked on the butt, cylinder, barrel and latch. Pinned blade front and notch rear sights, blue finish with casehardened hammer and trigger guard, bright trigger and fitted with checkered hard rubber grips with "S&W" monogram at the top.

Very fine. The revolver retains 80% original blue finish with almost all of the finish loss being on the cylinder, and loss is due to flaking. There is some scattered minor spotting and some minor muzzle and high edge wear. Almost all of the original bright case colors remain on the hammer and the trigger guard shows muted case colors mixed with a smooth gray patina. The grips are excellent with a few minor handling marks and crisp checkering. The markings are crisp and clear. The action is fine.
