My friend has a Stoeger-imported 12ga box lock marked Zephyr; it is indeed made by Victor Sarasqueta. Pistol grip, beaver tail, I think single trigger but I can't remember for sure. Some sort of crude game bird engraving. It seems a decent gun; he likes it. Don't know if this is the same gun you're speaking of.
