I'm 82% sure Mafacs (or any other modern brand of any nationality) will work, though you'll have to supply the 8 mm shaft, in the form of a bushing. Some precision is needed in cutting the bushing to length. It needs to be just a few thousandths longer than the brake bushing, for the brake to pivot freely without slop. This fit can be arrived at with no measuring equipment, by just grinding down the end of the bushing a little at a time between test-fits.

Hi Mark, thanks for the suggestions! What material would you suggest for the bushing: brass, plastic?
I haven't measured the distance between the post mounts yet, but that should also be an indicator. Old cantis used to be located closer together than modern ones intended for wide tire mtb-s.

I read somewhere that people have in such a manner gotten the humble, ubiquitous Shimano Altus cantis to work with the narrower spacing, but if my budget allows, I would hope to find something more period-correct.
These NOS CLB's, for example, have some good features, but the finish is not one of them... it's just hideous
