The LaGG-3

The profile depicts an aircraft of the 44 IAP in the Leningrad area,
probably in the early spring of 1942. "White 15" is clearly a very early
machine, possibly of the first several series. It appears to be a five-gun
model LaGG-3, and has had its sliding canopy removed (as seemed to be
quite common in the 44 IAP). The pilot of this aircraft is unknown,
but the photograph was found in the possession of the brother (Andrei)
of the 44 IAP's (11 GIAP) leading ace, Alexandr Savushkin.
The aircraft is finished in dark green and black/green uppersurfaces
and blue undersurfaces, with stars on the rudder and bottom of the wings
only.
