The B-24 was orignally designed in conjuction with us Brits and built for the RAF. The original naming convention was Mk I, II, III, IV, V etc with the "J" being a mk V.
The RAF flew almost all the variants of the Liberator there is a big Database on my site showing every Lib that we used (Find a Lib).
I got some colour plates of RAF, RAAF & USAAF Libs if anyone needs them for skins give me a shout. I also have colour plates of Lancs, Halibags (affectionate name) Wimpy (Wellington) and other Heavy Bombers and fighters as used by the RAF. If anyone's interested.
I've not played Aces High, I am however a propellor head and still play EAW. I waited over a year for B17 II because they said it had multiplayer only to find they dropped it
