That version of the G & H mount had a windage adjustment screw in the base for use with the pre-WWII German scopes that had only an elevation adjustment in the scope. Some scopes of that era and even after WWII came with 26mm or 26.5mm tubes. The distance between the top and bottom halves of the rings appear to be rings for 1" tubes that were adapted to use with the larger tube scopes. The rifle appears to be a well made modification of the 1903 Springfield. It would be nice to see a full length photo and hear more about that beautiful rifle.
