In looking at maps, old and new, we find the site “Wherethepath” to be really useful. It gives you the power to see different map formats, side-by-side, and to toggle between modern maps & old 1940s versions.
This a free site, (and OS impose a limit of 200000 map tile fetches per day”), but, if it runs out temporarily, the site will run with out of copyright 1940s OS Mapping. There is a version of this site without route planning HERE.
