This Il-2, probably photographed in 1944, is interesting because combines elements of 1942 (the plane itself and its camouflage) with other ones of late 1943/44 (the marks).
The white outline on its tail and some traces of winter finish make this plane even more interesting.
The base camo looks that of Zavod 30, modified with an extension of the black bands on the rear fuselage. This factory produced Il-2s with wooden outer wing panels.
It's possible, but not sure, that this plane was equipped with a dust filter on the carburettor's intake.
