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
What about it?
No
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..
Your Mauser model 98K rifle will accept and shoot the 8mm Mauser cartridge.For your own information,the letter code of SVW45 indicates that your German Mauser world war II rifle was made by Mauser Werke A.G. Obendorf-am-Necker in the last year of the War 1945.I hope that you enjoy your rifle as much as I do mine!I shoot mine at least once a month during the summer months.

"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.
7.92x57mm, better known as 8mm Mauser. Same caliber as the German military's Mausers.
