The most confusing for me was closer look to the photographs. Roundel yellow on both aircraft photographs was very dark and shiny – similarly to the fuselage band.

Gretza, the appearance of roundel yellow as a very dark colour in WWII photos is quite common, its something to do with the kind of film that was used and it gives this strange appearance to yellow edged roundels and leading adges. Its possible that the fuselage bands may have been in that colour too and came out dark on the photos. I would be quicker to suggest local over-painting of the band in the camou colour rather than red or yellow but it is possible. If its the same shade as the dark rendered fuselage roundel yellow then quite possibley it is the same colour.
