Hello kuduae,
Thanks for the reply.

While helping my friend with his Chr. Funk rifle, it was found that the Kahles Helia 862 has a front bell that is too large to allow removing the scope. In this instance, the claw mounts are useless. This is something the auction house that sold it, should have disclosed. I removed the scope by disassembling the rings and I installed the other smaller second scope that came with the rifle. But that scope was too dark to use, and the eye-relief was way out of wack, and you couldn't get your head back far enough to see through the scope to shoot.

However, I was able to purchase another vintage German scope on ebay. It was listed as a WW2 Germany Wabu Waffen Bultmann Heilbronn 4x36 81 Scope with a "rare" reticle. I had to do a lot of machining to make it work. I removed the bottom rails (like I did on my rifle's scope) and modified the claw-rings to fit the diameter of this scope's tube. It now can be removed and replaced with the claw mounts as it should be. It has a truly awesome reticle - like I've never seen before.

Would you have any info on this scopes maker?
