Hello, this item is a long-barrel single-shot firearm of unknown maker, likely from the late 19th or early 20th century. The extended barrel length and external hammer suggest it was designed as a hunting or fowling piece, possibly of European origin. The decorative metalwork around the lock plate and trigger guard points to hand craftsmanship, typical of rural gunsmiths working in regions such as Belgium, France, or Central Europe. The walnut stock shows natural wear, and the overall construction reflects a utilitarian design rather than a military application.

The absence of visible proof marks or serial numbers prevents precise identification, but the firearm’s design aligns with smoothbore percussion or early breech-loading shotguns. Considering its visible oxidation, surface wear, and rustic finish, this gun should be valued as a collector’s or decorative antique. Comparable examples of unmarked European long-barrel hunting guns generally sell between 150 and 300 USD, depending on condition and display appeal.
