Hello, this item is an American double-barrel percussion shotgun manufactured by Norris & Brother of Philadelphia, dating to the mid-19th century, most likely circa 1845 to 1865. Norris & Brother was a known Philadelphia firearms retailer and maker active during that period, producing sporting guns and percussion arms for the civilian market. The shotgun features classic mid-19th century styling, including a walnut stock with checkering, engraved lockplates and tang, exposed hammers, and decorative hunting dog engravings on the breech tang. The engraving quality and overall finish suggest this was a higher-grade sporting firearm rather than a basic utility piece. The percussion ignition system places it firmly before widespread cartridge conversion use in the United States. The engraved serial or assembly number “105” visible on the tang likely corresponds to internal production numbering rather than a formal serial system.

Condition appears fair to good for its age, with visible oxidation and brown patina across the metal surfaces, wear to the engraving, and age-related handling marks to the wood stock. The wood itself appears structurally stable with no immediately obvious catastrophic cracks visible in the photographs, though close inspection would be required to confirm internal condition and mechanical functionality. Collectors value these early American percussion sporting guns for their craftsmanship, decorative appeal, and historical association with mid-19th century gunsmithing in Philadelphia. Value is influenced heavily by bore condition, originality, and whether the firearm remains functional and untouched. Based on comparable sales for mid-19th century engraved American percussion double-barrel shotguns, the fair market value would likely range between $1,500 and $3,000 USD.
