That´s an excellent overwiew concerning the plane´s markings.

Interesting at first sight is the 3rd Gruppe vertical bar (or part of a fuselage band?) which appears as a vertical paint crack at the same position on the starboard side, parts of the splinter camo on the port side just behind the cockpit and some more red colour particles within the "yellow" area of "8".

It´s difficult to distinguish white from RLM 65 because hellblau seems to lose the blue pigments during weathering and withers to an almost light grey. I´ve seen several original examples having changed that way.

But no photograph can replace the personal view of paint cracks, the different thickness of colour layers and the personal observation which colour layer covers the other.

Professional examination of facade and wooden parts covering create some kind of "stairway" beginning with the younger layers as "upper stairs" and ending with the basic material as last - deepest step. It´sjust important to find a representative point where all layers are still preserved to show the succession of paint processes.
An eventual proof for an early-39 cross can only be gained by carefully sanding down parts of the grey paint - though some rectangular strructures beneath the strbordside cross may indicate this predecessor.
