Just checked. It is 122. A Stronglight 93 ring lines up perfectly with the Nervar chainring bolts. I have two other Nervars like this and they are both 122. So Nervar was changing to the 122 Stronglight circle at about the same time Stronglight was introducing the mod 106 with the Campy 144 circle, while Campy was abandoning 144 in favor of the smaller C-Record circle. Seems that French marketing was always one or two steps behind.
