This shotgun's serial number falls after the published serial numbers in W. Keith Neal and D.H.K. Back's "The Mantons: Gunmakers" and "The Manton Supplement," but like many of the late Joe Manton guns listed by the authors, it is a caplock 13 bore shotgun with detachable strikers and "JOSEPH MANTON & SON HOLLES STREET CAVENDISH SQUARE LONDON" marked on the rib. "The Manton Supplement" lists the last serial number as 11,500 in 1839-1842. The "I H & S" markings on the barrels and locks indicate Isaac Hollis & Sons were involved with this gun possibly updating it later and numbering it. Hollis & Sheath became Isaac Hollis & Sons starting in 1861. The underside of each of the barrels is numbered to the gun and has London proof marks with "13" bore markings and "I H & S" marks. The locks have "JOSH MANTON & SON PATENTEES" on the exteriors along with ornate scroll and border engraving, the serial numbers inside on the plates along with "I H & S," and the noted early style percussion hammers with detachable strikers. The furniture features primarily scroll and floral engraving. The trigger plate has a stylized pineapple finial, and the trigger guard tang has the serial number in large numerals. The wrist escutcheon is silver, and the breeches have platinum plugs. The stock has a checkered forend, tear drop flats, checkered wrist, and 14 5/8 inch length of pull.

Exceptionally fine with distinct Damascus patterns, 75% case colors, 60% brown twist on the barrels, minor oxidation, crisp engraving and markings, and general mild overall wear. The stock is very fine and has crisp checkering, minor scratches and dings, varnish crazing, and some spots of edge wear. Mechanically excellent. Overall, this is an attractive English percussion double.
