I'm looking for some things right now..
.....
IJN/IJAAF pilot gear/suit
USN/USAAF gear/suit
(I'm not sure, but I think AH default is USN..)
LW pilot gear/suit
VVS pilot gear/suit
RAF pilot gear/suit
.....
and an idea for more "generic" pilot gear/suit that is vague and mixed up enough to represent ALL of the above countries' pilot suits as one...

ps) you can really notice the pilots in newer model Spitfires are much more rounded up than the "Box heads" in older planes..
