Annabel used the name Mauser with regard to the cartridge, but didn't actually say it was a Mauser rifle, though one would get that idea. He was writing about this in the 20's, so of course there weren't .460 WB's, but, there were Rigby cases, and a .460 WB is just a .416 Rigby case with a belt added. Mr. Ratshooter, I have no way to send you a copy, but if you'll read some of Russel Annabel's old stuff, you'll read about it. It is mentioned in several of his Alaska articles that I've read, and I haven't read them all by any means. These were before he left and went to Mexico. This may be a dead end, as Rusty's deader than hell, has been for nearly 40 years. But I'd sure like to know what he was talking about. Barnsness is a pretty knowledgeable guy, so if you know him, maybeso you could discuss it with him in more detail, mentioning the source (Annabel, not me). I don't know the man, or I'd contact him myself.
