Hi,
I've seen the profile of yellow 9 published on
http://vvs.hobbyvista.com/DigitalModeling/monthly_profile/aug06/aug06.htmand I have some comments to add, having drawn a different interpretation of the same plane.
I can agree that light rectangles are more likely due to peeling of fabric skinning (so they should appear yellow) and not to repairing as initially thought.
However, I don't agree that the plane has to be interpreted as a simple mottling of light grey over AII green.
The first reason, of course, is that I think to see darker bands as drawn. You can judge it by yourself, the profile is aside two photos of the original subject.
The second reason is that some darker bands overposed to the light (grey?) color have a convex curvatute profile, as if they are painted after the light bands and partially overposed to them. So, the use of at least three colors is likely.
Besides, usually early type MiG-3s were factory painted with stars on fuselage and solid green uppersurfaces. Now, those stars aren't visible on the photo. Why should they have deleted the original star if they didn't widely repaint the fuselage sides? And why should them have repainted them with the same base color?
