Hello, this is my first post here, so I introduce myself. My name is Maurizio Di Terlizzi, a modeller from Rome, italy, so passioned in 1/32 italian, german and RAF fighters. I come across your very interesting discussion, and would like to express my opinion with a picture that is concerned to the example I choose to realize.
It is LE-X, of 242 Sqdn, serial P2967. As you can see in the attached image, "my" example too has a white/black wing, with BLACK??? fuselage underside and a light colour for chin panel. Following RAF rules, this kind of colouring must be BL/WHI with Aluminum chin and underfuselage, or the whole a/c with half in Black and half in white, or overall Sky, or overall Sky with left wing in black.
The images shown, plus mine, and the last posted (Hurri in flight), shows a further scheme....??!!
I think that two a/c had sky chin and underfuselage plus black wing, while the third, could be half black, half white, with the chin panel in sky. Why ? I don't know but this is what is evident from images....
Here is LE-X, please say what is your opinion. I clearly see that left wing, tailplane and tail wheel vertical fin are black, but chin panel IS NOT Aluminum and is not white.........
