Triples have to go back a ways as Jerry says.

What is significant to nail this down in the USA is a Schwinn Sierra circa 1963 or 1964. The premise of that model above a Continental was the triple crank.

So that's a run of the mill bike using the ubiquitous 116mm 3 arm cranks, in that case based on Ashtabula type arms. I would guess the rings were from Nervar.

I suppose in France the only limitation was flexible 3/32" chains starting from the early 1950's although you can imagine an attempt to get off the bike and engage a low gear by hand with a 1/8" chain on a small inner cog if the need arose.
