Antique Smith & Wesson revolver info needed
My great-uncle recently passed away and among his guns there is a revolver with a tip-up barrel. It is a .32 caliber with a 3 1/2" barrel, it is nickel plated with pearl grips and bears the serial number 58734. Along the top of the barrel it says Smith&Wesson Springfield, Mass. U.S.A. Pat'D Feb 20 77 Dec 18 77 May 11 80 Sep 11 83 Oct 2 83 TWO Aug 4 85. It is hammerless and holds 5 rounds. My father, who is 72, says that he remembers seeing the pistol on uncle Wes' bedside table as a child. My best guess is late 1880s manufacture timeframe. Any help would be appreciated...
