[CR]Strange Mafac brakes ID

Hi,

Could anybody help me identify these unusual Mafac Brakes? At least I think thy are unusual since I can't find a photo or description of them anywhere. I'm using them on my errand/shopping bike and they work very well and have lots of clearance, more than Raide's.

On a related note. I have some white plastic Mafac levers for upright bars. I was going to use them on my city bike as well. Are they safe? Are they rare and should I just keep them safe?

Thanks,
