+1 Really doesn't matter the brand of bottom bracket. Some french bikes from that era had french bb, some had Swiss, not many were using the british standard yet. BB cups will be marked differently depending on the threading. I've got a 1979 Motobecane with Swiss threading, I used to have a 1982 with Swiss threading, and I have another 1979 Motobecane with French threading....
