I have a Busch-Pressman Model D 4x5 camera (1940's I think) with a synchronized Meyer-Opticraft Rangefinder. I have been trying to fine tune the rangefinder in order to make it useable, but there is one problem I haven't managed to solve:
The secondary ghost image I see through the rangefinder moves vertically as I adjust the focus (and is vertically aligned with the main image when in focus), but the two images are slightly off horizontally.
This issue makes it a bit of a headache to focus, because the images are never truly aligned. Is this how these rangefinders are supposed to work? Has anyone run into this problem before?
Any advice, much appreciated! I'm not afraid of disassembling :)
