Well the 'N' certainly saw service in the Pacific war, so you could do it as one of those, and still get a'D' or 'M'. If you prefer 1/48th scale, I can thoroughly reccomend the Academy P47 kits - very nice indeed, and a cheaper alternative to the Hasegawa/Tamiya offerings, with a good amount of optional parts, including weighted and unweighted wheels, gunsights etc.
