Just another variation on undersides in the desert.
I spoke to a ground crew member that said that at some time they had to paint their a/c white sides and under the fuselage but they left the wings blue.This was relevant to Bisley's and Baltimores.
I have noted these different shades on photo's but never able to explain this untill he told me.
On some photo's of the Bisley's the underside was almost white which may have been early Sky, and some darker looking like Sky Blue or Azure Blue or even any of the 2 Mediteranean Blues.
I also have correspondence between Desert HQ and the units stating that Sky is the same as Duck Egg Blue, but I agree with the above sentiment that this must have been the later Sky Blue.
