Yes, kuduae is certainly a Mauser expert, and he has helped many of us forum members with his knowledge. Thank you Axel for your help.

With my new found awareness of J.P. Sauer & Sohn Sporting rifles, I just purchased another in 8x57 caliber. It is much more used than this 30-06, but looks interesting. It has strange bases for a scope that I have never seen before. I will post the seller's pictures shortly, followed by detail pictures when I get it in hand next week. Maybe someone will recognize the scope bases.
