I'm making a model of the Junkers Ju 52 with labels 1Z + BF CG2 / 4 Balkans in 1941.
What bothers me is that color is painted.

Italeri has suggested RLM 73 RLM 71 RLM 63

When Edward's proposal RLM 70 RLM 71 and RLM 63

I found one of his drawings, RLM 62 RLM 63 and RLM 71

Does anyone can help me, which could be a combination of colors?

Greetings!
