I went through the pics I have, but could not find any good shots of the fore end. However I'll have to make and send additional foto's later, as the gun smith is (now that I came back from the hunt) back in posession, to try the lowest mount possible with a Swarovski Z6i 1.7-10x42 SR. He said the lowest he'll be able to go, is 4.5mm above the quarter rib. That's where the ocular bell will start. From mid point of the old scope, to the mid point of the new scope, there should be less than 3mm difference. And since both will have claw mounts, I can switch back and forth. Once he is done fabricating all this, and has installed the new scope, I'll make additional pictures.
