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.
