My Poor 75mm Zeiss Biotar has a Problem

I had a bit of an accident with my Biotar 75mm. The lens rolled out of my bag. The newer M42 mount broke off leaving only the older EXA Mount. I have two adapters for EXA-LM, but the Exakta mounts definitely did not fit on the Biotar. It may be that the original Exakta mount was altered when the new one was fashioned. Or it is possible that there is residue from the new adapter such as cement glue? I don't know.

Any thoughts?
