The date code Z1 puts it at 1980 date of manufacture. A box lock with ejectors, straight grip stock and checkering on the butt instead of a plate or pad. Still cant determine the manufacturer. There is an emblem of an European style deer head mount with the letters RBI within a circle and many hours of googling and searching shows up nothing on it. Did find a picture of an action which looked exactly like it; a gun associated with Denton and Kennel [British Importers] who imported Spanish barrels and actions and then stocked them in England................but who made the darn thing???? Very nice fit and finish, fixed chokes, engraved roses and other flowers.....and 'Skinner Sports Toronto Ont' engraved on the barrels, but that could have been done in Toronto.....don't know. Weighs 6 1/2 pounds.
Did AYA make it or one of dozens of small gunmaking companies working in Spain?
