Not simple to translate as I am not at all a French speaker.
Making headway, but even after translation some words remain
For example, "Chemise" = "Shirt", which I think is actually cylinder? (Pistons-chemises)
I will continue the effort for quick reference but should probably expect to do a fresh translation directly from the original document before trying to order parts.
There were a lot of parts available beck in the early 70's.
I wonder what remains available today?
