I'm glad that you posted that fantastic colour slide of the tail of an Erla G-10 because that - to me - was the proof that the colour combination 75/83 (or 82) was used.
Beware however that the rudder colors does not mean nothing Erla-wise, because the rudder (and often also the whole fixed vertical part of the tail) were produced and painted directly as sub-assembled parts by external firms, which could well have RLM 83 available instead...
Such rudder however proves clearly (IMHO) that the couple of gray-green colors were used before or together with the 81/82 (or 83) pair as visible on other rudders.
What is fundamental is that Rasmussen could enlight us on what RLM colors (useable as camouflage ones) were available at Erla, because to be able to say what wasn't there, you should clearly know what
was there...
