Hi Milos,
and jeez, that's a lot of thought put into a single aircraft (and no, I will not discuss every single point of this^^).

First off: It was, is and will remain forever impossible to give any definitive statements about the colors in black-and-white photographs. You must always remember this simple fact before you get too carried away with speculations..

Then: Werknummer 380374 in Pilsen is almost definitely finished in a classical RLM74/75 scheme (or RLM 75 with a darker green). As 380352 was produced before this aircraft, it very likely also wore a 74/75 scheme..

Also: The colors of 380352, when photographed in Darmstadt, are much too faded to say anything of value about patterns, shades etc..

If I were you, I would put a 74/75 scheme on my model and live with the possible inaccuracies..

Cheers,
Christian
