Rifle Scopes Questions on older Kahles Helia L - 3-12x56

[jrhtx]

Anyone have instructions or info on this scope? Scope is 20-25+ years old. Photo is looking at the elevation adjustment, is the small screw at the edge of the center white a set screw to lock/unlock adjustment or a "fine" adjustment? Is the white tick mark in the black a "zero" point?
Any info is appreciated.

Do not remove either of those screws! Only use the center one to turn the turret to zero the scope, if it is not able to be turned with your fingers. Can you post a pic at a lower angle of the elevation turret with the cap off, so I can see if it has finger knurls or if you're supposed to use the center screw.

I can't find anything on a google search, so I'd contact Kahles US customer service to find out for sure before unscrewing things.

It does not have a way to turn by hand. Just the 2 screws shown. The cap screws down and nothing exposed to indicate elevation or windage "clicks"

And thanks for the reply.

Here's the manual: https://www.kahles.at/fileadmin/downloads/KAHLES_4x32_6x42_7x56_8x56.pdf

Push on the turret to create friction and turn it. Once you've made your adjustments, loosen the off-centered screw to rotate the index disk and mark zero.
