Has nothing to do with "buying the name", Kyrie. Simply referring back to your earlier contention about all those pre-WWI Spanish guns . . . none of which could have been made by AyA, since per your own post, the company did not exist prior to WWI.
Still in search of some of those Spanish antiques to compare to British antiques from the same period. I happen to own one of those. W. Sumners of Liverpool, 20ga, Damascus barrels. Passed reproof (3 tons) sometime between the mid-50's and the mid-80's. Bore diameter still spot on at .615, still in regular use with low pressure smokeless powder loads. Not a "name" maker by any means, but an example of a pre-WWI British double still in use--as are thousands like it, many of which also do not carry a famous name.
