Nope, no luck. My last remaining RELIABLE source gives James Norman Hall 3 victory credits.
It is not, however the last word. It also only credits Bill Thaw
with 3 Victory credits. And Thaw is known to have 2 more credits while in French service.
So, how about it, anymore for JN Hall while he flew with the French?
