Help Adjusting a Bessa R, Won't Infinity Calibrate

It seems that the center screw won't go anymore clockwise and this is the view at infinity lock on the lens. Turning the screw counter clockwise loosens it but has very little effect in the viewfinder other than slightly separating the double image and raising the mirrored image vertically (doesn't move the patch just the image).



The third screw at bottom (vertical adjustment) seems to have no effect and is already at the firmest position clockwise (counter clockwise will loosen it but doesn't change the double image).

No clue what's up with the patch screw at top (supposedly the patch clarity adjustment), it seems to either be missing or covered.




I know both lens are good (Canon 50mm f/1.8 Type-6, and Canon Serenar 35mm f/2.8) as I used the 50/1.8 calibrated for infinity on my Canon 7, and have done several rolls thru it with correct focus wide open.

Over on RFF someone suggested checking the closer focusing to see how close it gets.

1 Meter (~39.4 inches) on the lens, focuses at 36 inches on the RF.

7 Meters (~ 22 feet) on the lens, focuses at 14 feet on the RF.

Seems like I'm going to have to return it, neither screw does anything to the double image regardless if the lens is at 1m or infinity.

The previous owner only used ultra-wides with it, so he was unaware that there was any focusing issues.

Really sucks cuz I really liked the feel and look of the VF and wanted a TTL metering RF companion to my Canon 7.
