Well, youve picked 1) a rather nice looking subject there, but 2) a not very well known example; and as always Japo and EE agree on some stuff and diverge on others, regarding the D-13. However, given Crandall's involvement with Yellow 10 over the years, one must give his overview a decent amount of credence. But at the same time, EE seems to suggest that 836017 wore a base camo of RLM82/76, it also seems to state that 836016 wore RLM82/83 (EE volII, pg.285)
First, what is agreed on - RLM76 lower and RLM82 on the fuselage.
Second what is disagreed on:
EE - RLM82/83 upper fuselage colours (and presumably wing), RLM75 wing lower leading edge.
Japo - RLM81/82 upper fuselage colours, RLM76/81 wing camo and RLM81 wing lower leading edge. The updated Japo profile does appear to be hedging bets between RLM75 and 81 however:
Third, my gut:
Crandall makes numerous claims that the paint found on 836017 was mostly RLM76 (lower) and RLM75 (upper), so I feel it unlilkely that the next a/c in the production sequence would be finished so radically differently (of course to be fair and balanced, if the fuselage sub-assemblies were completed - and pre-painted - by different factories, that may explain this). BUT by that stage of the war, the combinations of 81/82, 82/83, 81/83, 75/82, 75/83 and pretty much any other combination you want to pick, are valid! To add further confusion, the different mixes of RLM81 (that are known) range from a Dark-Green to a Olive-Brown-Violet, so the Crandall interpretation of RLM82/83 may well be an aircraft in 81/82, where the 81 is the very green shade of the colour.
The conclusion is that as long as you follow the 'known patterns' on the a/c and retain the tonal difference that we see in the images, its hard to go wrong.
If I was going to paint this a/c, I'd likely be trying to decide between RLM81/82 and RLM82/83 uppers also (the general consensus seems to be 82/83 was an intermediate scheme and 81/82 was the late war scheme - however there is also an argument that RLM81/82 was the 'winter scheme' and RLM82/83 was the 'summer scheme'). You could also take the approach I ended up with on a D-11 (which happened by accident in fact) was that I ended up with a 'Dark Green' mix that is not quite RLM83, but is not far off the early 'green' RLM81 variants, allowing me to argue either! Sneaky, I know!
Hahahaha, I don't think I have helped at all, have I?
