I've managed to get the splinter camouflage scheme applied (when I should really have been working...never mind).
There's some confusion about this across the instructions, decal manufacturers etc. I doubt that there were several different schemes, but the lack of contrast in B&W photos makes it very difficult to interpret. Many aircraft appear to be in one colour when they are not.
I've gone with a pattern based on a 1940 factory drawing of this scheme. My subject was manufactured a little earlier, but I'm happy to go with this pattern.
This may be it for a while, but I'll revive this thread when I get going again.
Cheers
Steve
