About a week ago I was perusing the auction sites and I came across a Zeiss Zielvier from the pre-War era with a very strange set of rings on it. They extended some distance to the right of the scope tube and appeared to be fitted with female dovetails. Not until I saw the scope mount base on your rifle did I grasp what they were intended for.

I went back and scoured all the sites I had looked at, but evidently the auction was over and unlike on eBay, there is no way of finding the results of a closed auction on eGun. I'll keep my eyes open and should it come up, again I'll notify you.
