The colorization on the fuselage sides was applied freehand with a spray gun. The style of the shapes, color selection, and color opacity is up to the painter and the pattern is usually extremely random. Each plane would have been unique in this regard.
usually when discussing camouflage schemes, the word "variant" would be used to describe differences in basic patterns and not one-off
To me, what is most unique about this plane is not the camo on the fuselage sides, but the paint on the upper cowling being appearing to be RLM 70.
