Hello, this item is a single-barrel shotgun, likely a 12-gauge example, with a break-action mechanism and wooden stock. The firearm shows an aged patina and moderate oxidation, consistent with late 19th to early 20th-century production. The absence of visible maker’s marks or proof stamps suggests it was likely a locally or regionally manufactured hunting shotgun, possibly from Europe or the United States, produced by a small gunsmith or workshop rather than a major manufacturer. The plain styling and lack of embellishment indicate a utilitarian piece intended for civilian hunting or rural defense use.

Given its condition, with visible surface wear, corrosion, and stock staining, the shotgun should be valued as a decorative or collectible antique rather than a functional firearm. Based on comparable examples sold at auction, its market value ranges between 100 and 250 USD, depending on specific origin, mechanical integrity, and completeness.
