Drooling (come on, own up, I'm sure I'm not the only one!) over the Spitfire pictures posted by megan, I noticed that the two earth and dark green spits in formation have a different pattern to each other. This link talks of an A and a B pattern, but that they were merely mirror images of each other. That is certainly not the case with these two.

Any offers? I seem to remember reading that after one colour was applied, standard pattern rubber mats were laid over in order to paint the second colour. This would lend itself to a set pattern, albeit the colours reversed for an A or B pattern.
