My brother was recently doing so research on a family heirloom, an E.A. Prescott single action "Navy" revolver. This gun was manufactured sometime between 1860 and 1863 when S&W caused the shutdown due to patent infringment. This revolver is chambered in 38 rimfire and has 8 notches filed in the barrel. It was carreid by Gavin Young a Scottish immigrant who served as the "Night Watchman" for Marshall, Texas. This gun was on display at the Alamo museum during the 1960s. Before this recent research we had never known the tie to Smith & Wesson.
