Thank you Tracker, but there's a misunderstanding! Sorry, my fault: I should have better describe that I was speaking of Imperial JAPANESE Army Air Force!
Indeed, there's an almost total lack of this kind of info about Japan Army fighters (found some partial and unconfirmed data about Japan Navy fighters, thank to a Japanese friend, time ago), easily explained by destruction of original documents at war end.
It is quite easy to get American figures (Army, Navy, USMC) by plenty of dedicated manuals (like that you pointed out), aircraft manuals and so on. Also enough available similar material for Luftwaffe. Oddly, I was unable to find anything also about RAF fighters: apart a hint somewhere by Tony Williams, no official documents look still declassified!
Cheers,

BTW, would be really GREAT if on this forum an user wouldn't automatically logged out every ten seconds or such; being English not my language, I spend a while to compose a message, during which I'm forced to login over and over...
