According to AR, the planes shown in this screenshot could be of 2nd Polish ShAD (the Polish personnel unit within Red Army).
The first plane is a straight-winged one with short radio mast; the camouflage and markings are of the type introduced in August 1943, while few time later a tall antenna mast was introduced into production, aside new streamlined rocket rails.
The shape of the hood of the tail wheel suggests that this plane was built in Zavod n.1 and had wooden wings.
The use of blue for the spinner and number is hypothetical, they looks too dark to be white as the outline of the star on the tail.
The second plane, white 7, seems to have a long radio mast and stars of different size and a different tail wheel hood; it seems to be built from another factory, perhaps z.18, , so it could have metal wings; besides it wears the other camo pattern.
In the photo above: another Il-2 built in Zavod 1 in the same period, very similar to 'blue 2'.
Belw: my drawing of plane n.2.
Any suggestions?
As usual, Jason, if you want the drawing for your book, I'll send to you an higher resolution version.
