Check the Pic below. I have seen different roundel diameters used on Spittys, but these appear abnormally small. What do you think ? Were there standard propotions to be used by the RAF ? Also, there appear to be two of them on the fuselage, what's that all about ?
And lastly, is the white stripe on the wing considered an invasion stripe, what is it's significance ? I'm in the process of finishing my own, and I'm looking for some accurate information regarding roundel diameter standards. Were there any ?

Thanks for your help.
