There exist three photos showing three apparently identical fighters, numbered 44, 45 and 46; they are late production types, armed with rockets, flying with open canopy and open rear undercarriage with doors open.
The spinner looks unusually pointed; probably it has the tooth for the starter.

The camouflage is black and green, and is representative, with small variants, of the camo scheme of many MiG-3s.  The hand painted digits look to be silver, and are not perfectly parallel to the flying axis.
