I bought a used bike and it had these clipless pedals with it.

I have some look cleat that seem to fit in it, so the pedals probably use a look mecanism (plus it is written "product of France"), but I'm not sure they are look pedals, because they are old and I heard at the beginning of shimano's clipless, they used look patented mecanism. To me, the pedals seems more shimano-ish than look-ish, what do you think ?
Oh yeah by the way, there is no brand logo visible or anything like that, only some traces of black ink where the pedal is the most used.
