This early percussion shotgun has a lock and breech arrangement similar to a single barrel sporting gun (sn 10.112 from c. 1828) shown as figure 99 in "The Mantons: Gunmakers" by Neal and Back and is also similar to some of Mantons earlier pellet and paper patch ignition guns. The locks are signed "JOSEPH MANTON/LONDON" and have engraved scrolling serpents and removable strikers. Coordinating serpents are engraved on the trigger guard bow and heel of the buttplate. The breech end of the rib, the upper tang, and other areas have scroll engraving. The barrels have "JOSEPH. MANTON" marked on the rib, London proofs, and no serial number. The breeches have platinum plugs. The stock has German silver escutcheons, a smooth forend, checkered wrist, and a 14 inch length of pull. The case has the Fleming crest over their motto "LET THE DEED SHEW" on a belt and the initials "R.S.F." on the lid escutcheon, a Manton trade label, punch, two cap tins, a leather shot flask, and a brass powder flask.
