Red/white 4 is the best photographically documented Il-2 remarked by Germans.
The first photos represent it still in Soviet marks, and are an excellent document of one of the variants of the black-green camo utilized by Zavod 18. The red star with thin white border on the tail is typical of Zavod 18 too, while the black outline of the star on the fuselage (instead of white) is unusual.
The wing is metallic, as typical of this factory, has balance horns at its tip and the fairings of the VYa-23 guns (whose barrels are not visible because the weapons were removed).
The first image suggests that it could have a curved-type aiming device on the left side of the nose, but this don't appear in other photos.
The first photo show the same plane with Soviet marks deleted (unclear if with Soviet or German colors) but not yet remarked.
The following images show the plane in full German marks, with yellow band on the fuselage (and presumably under the wingtips). The strange inclination of the swastika on the tail and of the crosses on the fuselage is noteworthy.
The latest image shows the plane with the guns reinstalled on the wings by Germans.
