RE: the Great Pink debate (or not)
Oh never mind....all I was suggesting was that it is far from impossible that the P-40 may have been painted a hue that had a pinkish tinge to it since there are other, period and up-to-date, examples of equipment painted in such a fashion - nothing more.
Call me devil's advocate if you want.
Hope you bottom this issue. If I were you, I would just paint it as you see fit and the naysayers and rivet counters be damned!
Happy modelling!
cheers
