Best and needed aircraft books opinion ?

[MarkCY]

Being in the process of having to sell the majority of my library, am curious what others think are some best or favorite WWII aircraft or aerial related books among their libraries. Also what needs done regards topic

6 that come to my mind at the moment:

1) Green, "Warplanes of the Third Reich" (a 1st edition photo quality)
2) Mason, "Battle Over Britain"
3) Bowers, "Fortress in the Sky"
4) Francillion, "Japanese Aircraft of the Pacific War"
5) Warner, "The Bristol Blenheim, A Complete History"
6) Obermaier, "Die Ritterkreuzträger der Luftwaffe," 2 volumes

Aircraft that I'd like seen done in great detail and quality:

1) Martin Maryland
2) Japanese Zero (and numerous other Japanese aircraft types in ENGLISH)
3) F6F Hellcat
4) A-20
