This is an antique percussion side-by-side shotgun in 10 gauge, with barrels measuring 30.5 inches to the breech plug. Both side locks carry the marking Rudolphe Brauns Patent, dated April 17, 1866. A gold inscription on the rib reads Fine Damascus Steel, and the Damascus pattern is described as very clear and well done. The listing ties the maker to Augustus Braun with Rudolph Braun of San Francisco, citing Frank Sellers' book American Gunsmiths.

Percussion ignition makes this gun a muzzleloader, and Pennsylvania's deer and bear rules list muzzleloaders as legal arms. Its main appeal is as a collector piece, where the side-lock markings and the Damascus rib are the details a buyer will study first. The condition is listed as used, and the gun is classed as an antique built before 1899.
