Interesting discussion!
Here is another pic of that plane.

1 and 3 are RLM 62 green
2 is RLM 61 Brown
4 is RLM 63 Grey
but have a closer look at the C24 marking.
At the top you see RLM 61 but the base of the letters was overpainted with 2 different colours. Maybe RLM 02 and RLM 70/71/62???
Cheers,
