Moore's Patent Revolver (Swing-Out Cylinder)
The Moore's Patent Revolver, produced from 1860-1862, was the first commercially available swing-out cylinder revolver. It fired a .32 Rimfire cartridge and was used by Union soldiers during the Civil War. Despite its innovative design, it infringed on Rollin White's patent, leading to its production being halted by Smith & Wesson, making it a rare collector's item.
