Hi,
here is a photo of Il-2I ( Istrebitel, fighter) of 1943.
It remained ony a prototype, neverthless it's interesting for two reasons:
-the blue grey- dark grey camouflage typical of fighters of late 1943, following the same template as Yaks and Lavochkins;
-the arrow wing combined with an earlier singleseater fuselage.
It could be a good way to utilize the spare pieces after kitbashing Il2 and Il-2M3 to obtain an Il-2M (I know that these names aren't official, but they are widely known).
Regards
Massimo
