I'm tired of fighting with the Hugo Meyer RF on my pre-war Anny! It's the right model for the lens mounted, and can be set up and calibrated. But if I leave the camera in the closet for more than a week it somehow drifts out of calibration. I obtained another pre-war Anny for parts, and it has a nice Kalart RF. Anyone switch these? I haven't pulled both RFs off the bodies, but at first glance it seems that the hole through the body is drilled in a different spot. There must be installation instructions out there somewhere, and/or templates to drill the hole. Can anyone help?
