A picture comparison of the receiver bridge of a Brazilian m1935 and a German K-98, it would appear you can use the 3 bump chargers mentioned by Eaglelelord17.
The width of the chargers may be an issue, check the two rifles mentioned.
I think that the Mauser cartridges, 8x57mm, 7x57mm and 7.65, all use the same basic case before neck and length resizing.
