Ed, I can only wonder how the Spanish made guns that Ernest Hemingway either used himself, or gave to friends to shoot, made in Eibar, held up. Hemingway used all his guns hard, demanded reliable performance (his favorite esopeta was his 1928 era M12 12 gauge) and of course, was in love with Spain and Spanish speaking people. heat treating standards may have varied from one European country to another back in Hemingway's days- also, if I am correctly informed, many of the Spanish gunmakers did contracting work for the London makers.
