Here is an interesting photo of an Il-2M after a crash landing. The photo was probably taken in winter 1942/43, when the two-seater version was just introduced into units.

Unfortunately the photo doesn't allow to understand which factory produced it and if it had metal wings or wooden ones, so I've guessed that it was the typical production of Zavod 30 with wooden wings. In this choice, I've considered that the photo doesn't show any trace of the typical white outlines on the stars typical of Zavod 18, the only one that produced metal wings at that age.

The most interesting fact is the way how the white layer was applied: we can see that the well covered parts are forthemost those well visible from above, while the parts visible mainly from the sides have a more greyish look due to unperfect covering. This agrees with the fact that white paints camouflage well the plane on a snowy ground, as seen from above, but makes it too visible if seen against any other background, as seen from the side.

One must say that, while the full-white tip of the tail is undeniable, the different shades of white over the wings and tail could also be due to snow deposed during the forced landing.

Another interesting thing is the low-visibilty fuselage star, covered with a thin layer of white paint giving a pinkish shade; an external outline was left unpainted and appears as a dark shape to put the star more in evidence without making the plane too visible.
