... silver/grey Su-2s could be added to the page of 1940 planes.
you should add Su-2s made in first 6 months of 1940 to your
1937-1940 page. IMHO, those planes were
light gray overall, same as SB bombers made at the same time. Only about 30 planes were painted in this scheme - they should be extremely rare!!!
... I have found a pair of photos of an overall silver Su-2 in 1942, flying aside two camouflaged ones. It's a famous movie, I suppose that you could have already seen it. It shows a silver cowling too, only the foldable panels behind the turret are darker. The persistence of this painting is surprising.
1942 plane is more likely representative for
winter camouflage! Or some field improvisation, I would not mix that with
1937-1940 scheme!
Ivanov M-88 looks cherry red as Yak and I-301 were supposed to be.
or just "protective green". Yak and Lagg prototypes were mixed construction/wooden planes and were treated different than all metal Su-2 prototype.
