Nice! The rounded grip/finger-groove fore end combo is a traditional German style - a favorite of mine, too.
The model 60 is the long-barrel version of the famous BSF 55 carbine. If in good fettle it should shoot significantly harder than an HW 30/R7. The 55 was about the hottest-shooting springer of its day.
Back in BSF's heyday of the 60's and 70's, the 55 and 60 came in a standard version with a slender finger-groove fore end beech stock, and an "N" version (i.e., model 55N and 60N) that had an identically-shaped stock in walnut. The model 70 was the same action with a fancier cheekpiece stock IIRC.
