Here are two low-resolution images of the same Il-2 belly landed on the snow.
For what one can understand on the images, the white winter finish cover all the horizontal surfaces, while the fuselage has a disruptive scheme. On the rear fuselage and tail, the white paint seems to follow the lines of the black bands of the typical camo of Zavod 30 (plus some green). The sides of the fuselage are confused because of wearing and fumes, while the nose looks to have a strange division line between and black, and a clean white band behind the spinner.
The wings are wooden, coherently with the hypothized origin of Z.30. The fuselage star is in low position, a thing already seen on the planes of this factory, while the red star on the tail is slightly shifted forward, not centered on the rudder hinges line as usual.
Having z.30 started the production of Il-2s in the spring 1942, the photo can be dated in the winter 1942/43.
The plane is drawn with the dust filter on the intake, as sometimes seen on late singleseaters, but its installation is not sure.
Thanks to Istvan Vadasz for the photos
