This Colt Model 1851 Navy style percussion revolver was manufactured by Samuel Griswold in Griswoldville, Georgia, c. 1864. Griswold revolvers were close copies of the Colt Model 1851 Navy with a distinctive brass frame and round Dragoon style barrel. Griswold only manufactured approximately 3,700 revolvers for Confederate government contracts from 1862-1864. This revolver is a "Second Model" with half-octagon barrel housing. The brass frame has a large capping cut-out in the recoil shield that lacks a capping channel. The cylinder has six stops and safety pins. The twist lines which are a distinctive feature of Griswold revolvers are barely discernable due to the high condition of the cylinder which still displays most of the original milling marks. The wedge, correctly, lacks a spring. The hammer has deep hand-cut knurling on the spur. The full serial number is stamped on the cylinder, right side of the frame and right side of the barrel lug. The secondary serial number or assembly number "22" is stamped on the loading lever, back strap, trigger guard, wedge and on the internal portions of the trigger guard, back strap, trigger and hammer. A reversed "Q" is stamped on the inside of the frame, trigger guard, back of the frame, bottom of the barrel and back of the cylinder. The Roman numeral "XXIII" is stamped on the inside of the frame bottom, back strap and trigger guard. The barrel and cylinder are blued, the loading lever and hammer are casehardened, and the frame, trigger guard and back strap are natural brass. The one-piece grip is oil-finished walnut.
