Extremely Rare Engraved, Gold Inlaid, and Silver Mounted Forsyth & Co. First Model Sliding Lock Percussion Shotgun with Hallmarks for 1822 Reverend Alexander Forsyth was instrumental in the development of use of fulminate of mercury as a replacement for black powder as an ignition source and is generally considered to be the inventor of the percussion ignition system. This incredible early percussion gun features Forsyth's distinctive first model sliding primer mechanism. The smoothbore Damascus barrel has a gold bead front sight with flush inlaid gold "spider" base, girdled transition, and extensive gold inlaid foliate and martial trophy designs on the breech section, including an escutcheon signed "FORSYTH/& CO" on top. The underside of the barrel is marked with Birmingham proof marks and "Damascus", and "2899" (9s look like upside down 5s) is marked on the breech plug hook. The standing breech has a grooved rear sight with a gold crescent moon and three stars along with additional gilt foliate and star patterns. The lock is decorated en suite and has gold foliate and martial trophy designs and "FORSYTH/& CO" signed on the drum at the center. The mounts are silver with cast foliate and classical martial patterns. "SC & Co" silversmith's marks and Birmingham hallmarks including the date code "y" for 1822 are struck on each of the primary mounts. The figured walnut half-stock has a checkered wrist and a 13 5/8 inch length of pull.
