Those swastikas are what make the value of the gun... They're just marks on metal bud. 
As for an 8mm mauser, that is a downright light recoil compared to a .338 lapua without a brake. The 8mm Mauser (K98) recoils with 12.9 ft-lbs of energy to your shoulder with standard 170gr ammunition, the .338 Ultra Mag (fractionally less powerful than the .338 lapua) with 43.1 ft-lbs... Roughly 350% of the recoil of the 8mm you're familiar with. Just practice and prepare yourself for it, as compared to standard cartridges, it's a whole different level, while manageable with practice.
