Hello, this item is an antique long rifle, identified by the engraved name “Newman & Davison” on the barrel, which suggests manufacture by an English gunmaker active in the 19th century. The rifle features a flintlock or percussion mechanism (from the images it appears to be percussion), ornate side plate engravings, and a figured walnut stock with an inlaid silver escutcheon engraved with a bird motif. These stylistic details place it in the category of custom sporting rifles produced in Britain during the early to mid-19th century, likely intended for hunting or sporting use by the gentry. The presence of decorative engraving indicates it was a higher-quality piece, not a basic utilitarian firearm.

In terms of market value, English sporting rifles by lesser-known but documented makers like Newman & Davison generally sell in the $1,200–$2,500 range, depending on condition, originality, and decorative features. Well-preserved examples with strong provenance can reach higher values. Since this rifle shows intact woodwork, engravings, and fittings, with no visible major repairs, it likely falls within the $1,500–$2,000 range at fair market value.
