I recently managed to purchase this Schutzen rifle out-of-the-woodwork.
The overall length is approx. 50" and the weight is about 12lbs.
The barrel is marked Otto Zettlinger on the right side.
The barrel is marked Eichstatt Bayern on the left side.
The drop block appears to be marked "SYST AYDT".
I'm guessing the caliber is 8.15 X 46 or therabouts but I will do a chamber cast to verify this.
The overall condition of this rifle is truly excellent.
I would appreciate any information my fellow forum members can provide.
I will try to take some better pictures as the light isn't great right now because the engraving and workmanship on this rifle is exceptional.
