Don't have a pair now, but my recollection is that some Weinmann/DiaCompe levers had a threaded hole in one side of the body to accept the mounting bolt for the safety levers. A lot of Weinmann/DiaCompe hoods even have a perforated circle that can be punched out for this mounting bolt. I guess Mafac didn't want to drill their lever bodies, or maybe the shape or the amount of travel of the Mafac levers didn't work well with the safety levers.
