Hi Larry,
Not much time left to put me in ...
But Dumollard's book was in my mind as obvious and first source ... though being in China ... far to be reachable
...
As for "Vélizy-Villacoublay"; It's actual name though I don't know if it was in use during the 40s - I'm quite sure it wasn't.
But maybe a clue to differenciate Villacoublay and Villacoublay-Nord in use at that time. (Like Buc, Toussus and so on in this "crowded" area)
Note that "Le Musée de l'Air" had its "reserves" down there during years, I'll be surprised if you don't find answers with them.
Regards, Franck.
