IIRC Mauser claimed the 9.3x62 was their own invention; they did refer to it as "our 9.3x62" in pre WW II catalogs. Again IIRC, the tradition of Otto Bock being given credit for it started with Frank Barnes and his first edition of Cartridges of the World. One of the other forums, possibly African Hunting, had quite a discussion several years ago on who came up with the round, and it ended with Mauser as the winner.
this is only in North America about 9.3x62 mauser in europe they say 9.3x62 with development done by a gunsmith with the name of Otto Bock.
in the time of our gun registry i had a rifle registered with 9.3x62 mauser for caliber i tried to explain to the shop where i buy there is no such a thing. useless needless to say lol.
