Hello I'm new to the forum and have a very nice Spanish SxS. It's a 20 gauge with 2 barrels and was manufactured in 1961. It's an engraved side lock with self opening action with sideclips and gold inlays. The action and barrels are very similar to a Pedro Arrizabalaga but I can't find a makers mark. Barrels are 26" ic and ic choke and 30" full and full choke. Any help would be greatly appreciated.     Thank you Paul Schaeffer
