Hello, this item is an antique side-by-side shotgun by J.P. Clabrough, a Birmingham-based gunmaker active in the second half of the 19th century. The company was known for producing high-quality sporting arms with fine engravings and durable mechanisms. The example in the photo shows a sidelock action with decorative engraving, double triggers, and an overall length of 46 inches. The mention of some rust on the barrel is significant, as condition plays a major role in value.

J.P. Clabrough shotguns are collectible, particularly those in good working order and with preserved finishes. Depending on grade, condition, and originality, they can sell in the range of €1,000 to €2,500 at auction, with higher values for better-preserved and finely engraved pieces. Given the rust and wear noted, this example would likely be valued closer to €800 to €1,200 unless professionally restored.
