OK, here it is. Half round, full matted rib. A slightly shorter and lighter barrel than the 7mm one on the rifle. Dies (6.5x57 Hornady) and brass (7x57R Prvi) are on the way so I'm being optimistic that it will fit the action. The scope is adjusted for windage by driving the dovetails. It has a post and horizntal crosshair. I'm guessing about 2 1/2x. It was proofed in Suhl in August 1933 with a 123 grain bullet..

The Zeiss ZielKlein was the German equivalent of our Lyman Alaskan. It is apparently 2.25x and came out around 1930. To focus it, you slightly loosen the 2 screws on the eyepiece and just give it a few degrees turn until sharp and resnug the 2 screws. It is still clear as a bell after 90 years. It was used on the German sniper rifles in WWII and because of that brings a premium when it shows up on the market. I just remembered I have a German over-the-shoulder pigskin scope case that was made for a claw mounted scope and I checked the length and it is perfect and oblong in shape to clear the mounts. I won't need it until I have to take the scope off to see if the barrel will fit my action. Fingers crossed.

How smoothly does a Heeren cycle, say compared to a Ruger No.1 or a Hagn? I've never handled one, but I do admire the compact design.

Thanks for the description. The Hagn seems effortless, with no stages, if I can describe it so. The Ruger is low effort, but you feel a few stages, the last one with the lever going limp. The short throw on the Heeren suggests it will be stiff, but there appears to be a few variations in how the mainspring is done in the Heeren as made by various makers.

You mention opening it with the thumb. Oddly, I always imagined opening the action by flicking the wrist forward and having the trigger finger unlock and throw the action. Depending on how stiff is the mainspring, I can see doing it so could soon make the side of the finger sore.
