Hi Lancaster, that's the photo.

I hadn't noticed the A-5 earlier. I don't know why two men would be carrying rifles and the other a shotgun - maybe just a staged photo?

As to the location of the shot, those rocks are likely still there wherever it is.

As to the Mauser, I guess the question is whether it's a magnum action. Seems so to me but it's very hard to tell from photos (for me). If it's not a magnum action, it could be a 9.3x62 or 10.75x68. The cartridge belt appears in the photo but is of no help unfortunately.

Speed notes that there are records of 6 Mauser B's in 8x75 being delivered to 'customers' in southwest Africa in the 1930's, seeming to imply that those are the only records of original Mauser sporting rifles in that caliber. Not sure what he means by southwest Africa and why he didn't name the country. Modern day Angola, Namibia? Botswana or the western part of South Africa?

It seems there were no cheap rifles built in 8x75 - only original Mausers or other very high quality German arms.
