FL vintage ribbon microphones information???

Hello there,

I was wondering if anyone has ANY information on the history and provenance of FL MICROPHONES.

They are vintage ribbon mics and I think they might be French but I can't find any information on them online.

Attached is a picture of one.

I've seen this model called C109 or PM111 but I don't know which is true and whether it's correct a all.

Any info is appreciated
