I would say the distance shown between the end of the prism case and the edge of the adjustment knob to too long for this scope to be a Goerz Pernox 3.5x. I believe it must be an earlier type of Pernox or a Hensoldt Solar of some type.

Obviously a sporting rifle. Did the Austro-Hungarians requisition scoped sporting rifles as was done in Germany?

The mounts look terribly flimsy and very high, even for that time.
