This image represents a LaGG-3 of the 3 Gv.IAP of Red Banner Baltic Fleet during the winter of 1942/43, east of Lake Ladoga.
The aircraft was probably of 3rd or 4th series, and its characteristics are:

• sharp prop spinner;
• tubular exhaust stacks;
• 1 ShVAK 20 mm firing through the propeller shaft;
• 1 12,7 UB machine gun guns on the left side of the engine cowling, and relative holes on the left side of the cowling;
• 2  7,62 mm ShKAS machine guns on the engine cowling;
• engine cowling with dzus lock and unusual vertical intake profile; this could be due to some repair after a forced landing;
• rounded (?) side plates behind the exhaust stacks;
• rectangular (?) supercharger intakes;
• short radio mast;
• straight rudder with two balance masses;
• water cooler outlet on the fuselage with small step and flap without rear extensions;
• fixed tail wheel;
• no slats, pitot on the right leading edge;
• removed sliding hood;
• removed wheels doors.

This aircraft is characterized by:  MK-7 white distemper over a not well identified temperate scheme ( a typical 1941 scheme was hypothized);  having been built and painted in 1941, black paint can be hypothized as worn and turning to grey; red stars on 6 positions; the ones on the rudder are unusually small, painted over a particularly white spot, probably over the white paint;  other stars are painted over the base camo, even if the fuselage stars are unusually moved back; white 64 painted on the sides; black prop blades.
