I recently bought a Franz Sodia SS made in 1964 with claw mounted Hensoldt Wetzler Dialytan 4x scope. The scope has both windage and elevation adjustments on it and I am pretty sure from examining and shooting the gun that it was unfired when I bought it. The adjustment turret heads have 4 screws each on them and one of the screws is silver colored and the rest are blued to match the head. I am thinking the silver one is a locking screw and it must be loose to turn the heads. Can anyone confirm this to me or have any experience with the Hensoldts of the 1960 period or do you know someone who could advise me.
Thanks,
Dave H
