This is a very pair of Grierson 64 bore percussion overcoat pistols. The barrel is marked Grierson Gun-Maker 10 New Bond Street London. The bore and mechanical function is very fine plus condition with both hammer safety’s functioning. These pistols are well over 80% original finish. The wood retains over 92% varnish. One ramrod is a replacement. 64 caliber up close and personal would hurt very much. The barrels are 5” long and 10 ½” overall in length.
