I have a Beseler 4X4 lens mounting board which I have modified for use on a Omega D-2. I did this by hacking off a corner so it would fit on the Omega board. It has worked famously for years, but now I wonder if I have ruined it forever for use on the Beseler as originally intended. I do not know enough about the Beseler's to know. Please see the attached jpeg to see what I mean. Any advice will be appreciated.
