Depends on what you want to do with the Mauser- hunting or target shooting. Hunting scopes are usually limited to between 4 and 9 power, target scopes may run 24 power. Would suggest you find a good neighborhood gun shop, and discuss what your uses are, and see what they suggest. Higher power equals smaller field of view. Too much power, you won't be able to find the animal in the scope.
The 8mm Mauser is a good black bear round. American 8mm is kind of underpowered but with handloading or European ammo its in the same class as 30-06..
No- the 7x57 was developed separately, in 1892 by Paul Mauser. The 8mm Mauser (actually the 7.92 Mauser, but every calls it the 8mm) was developed by a government board.
Numerous commercial and custom makers have made 8mm Mauser rifles in the last 100 years

"No, 7.92 is German military caliber for WW 2 and earlier Mauser rifles." Actually, 7.92x57 is the same thing as the 8MM Mauser, if that's what the person was asking.
You need a professional appraisal. Could be in the 100-10000 or more range
7.92x57mm, better known as 8mm Mauser. Same caliber as the German military's Mausers.
