M Lens to C Mount Adapter?

Can anyone recommend a source for an adapter to allow for mounting of M lenses to Bolex C mount?

Bonus question - does anyone have any experience shooting with M lenses on Bolex? Any other considerations?

I have a few of these and would like to leverage them if possible.

Thank you,

I haven’t seen any adapters, probably because if a lens protrudes past the mount (as some M mount lenses do at infinity) it wouldn’t fit through the C mount opening. Either that, or there just isn’t enough space between the bottom of the M mount and the flange of the C mount - there’s only 10mm difference in flange depth. Usually if it’s possible, someone has made an adapter, but in this case none of the usual manufacturers have.
