I have an atlas from the early 1950s and while not as "up to date" as a prewar atlas, it'll probably be a LOT more accurate than a modern one. If you are interested I can scan the relevant pages of the south of Holland for you (main roads are also marked on it) i.e. everything south of Arnhem.

Thanks Gerrit, but I think Holland is now covered by recent good quality info I've received.
The main areas where I don't yet have historical info is France and Southern Belgium.
