On the opening page he has one of them which he has captioned:-
A pink Spitfire PRVII, probably P7505….
He is usually correct. 🙂

But not in this case, I am sad to say… (“Good Mourning”?) You can see clearly the early type (‘A’ style) roundel in the photo, while P7505 was not converted for PR duties until 1943, apparently. Sometimes it is the most difficult to see the most obvious things.
I’ll talk to the publisher, and hopefully they’ll have an erratum on this one in the part II they are planning. Especially as, apparently, the man in the cockpit is no longer anonymous, so his log book might provide a clue as to the real serial.

Flying High, despite the miscaption, the book might answer many of your questions.
I am experiencing problems with my PM inbox (something to do with my age?…). If you want to contact me off line, PM Mark(s) or JDK to tell you how to do it.
