Adam, I think that you will find that those Mauser's made before WW1 are of the highest quality, especially the 1908 and 1909. The 1908 was chambered in 7x57 so it will handle that round without any problems.

That Rigby Mauser on the Auction site is what Rigby referred to as the No.3 model which had a 21 inch barrel and was built lighter for ladies and boys. They could be had regulated for either the 175 grain or the 140 grain. Very nice little gun.
