The two-stage, smoothbore barrel has a silver "spider" base front sight, and carved "wings" flaking the barrel tang function as a the rear sight. The barrel has turned girdles and chiseling at transition point and a sunken "crown/MA/CA/MS" marker's mark along with a sunken gilt crown marking and brass inlaid designs at the breech. The lock is signed "G. MASPER" (c. 1750 per "Der Neue Stockel") behind the cock and has scroll engraving. The carved wood trigger guard has an "RM" monogram inscribed on a silver oval inlay. The barrel band, heel extension, and reinforcement plates are silver. The heel plate is iron. The forend cap is horn and has decorative carving that continues along the edges of the forend. The figured stock also features a panel of checkering on the forend, scroll carving, molding, and a distinctive "Madrid stock" fluted butt.

Good. This Spanish gun appears to have been used in combat given the deep strike line on the barrel suggesting it was used to block a blow from a sword or other edged weapon and has period silver reinforcement to the wrist and breech section, possible to repair damage from when the gun was clubbed. The barrel retains 20% of the original brown finish, and the balance of the iron has gray and brown patina. The maker's mark on the barrel is missing its gilt lining. The silver throughout displays attractive well-aged patina. The stock has very attractive figure, crisp carving, mild scratches and dings, and some cracks and repairs. Mechanically fine. This is certainly a very interesting Spanish piece that leaves you wondering when and where it was used.
