Is there a chance you might know what kind of maps of Europe he may have used? I'm thinking of something that the maps of Middle-earth might be based on; whether merely a subconscious influence to an outright tracing.

No idea. The only page I know of that diary is the page shown in Maker item 87.

And today I note he might have used another source for his moon rise and fall time (because the 1941-2 diary only shows sun rise and fall time, plus moon phases). That's Marquette MSS-4/2/29/18a shown in Tolkien: Voyage en Terre du Milieu Fig.189 ( https://twitter.com/zionius/status/1486565751788310530) It says "based on Moon-hours(?) May 6-15 1944". The date exactly matches Letters no.69 on May 14 1944, where he said he spent hours trying to fix moonrise/set time.
However, the moon rise and fall time recorded in that manuscript doesn't fit the actual time in May 6-15 1944 at all. So I still don't know how he got those numbers.
