Its characteristics seem to be:

• early type example, without slats;
• with radio mast;
• it wears a yellow 6 on the rudder, but it has a white  number with two digits (4 and a rounded digit, hypothetically 0) on the fuselage side;
• green base camouflage, with dark green field applied bands, with rough black repaintings, extended on light blue and red stars too;
• bomb racks under the wings; 
• the underwing ammo doors look sealed with dark adhesive tape;
• fixed tail wheel covered by a light blue tissue cover;
• green spinner, probably with some small black repainting;
• green and/or black painted propeller blades (I think green with small black repaintings).

A previous version of the centre photo was too contrasted, and seemed to show the aircraft with white wings, moving on a snowed surface, and armed with rockets.
 

• what is visible on the photos, with special regard to the wings leading edges;
• the presupposition that the aircraft was originally painted with overall green uppersurfaces, and had red stars on the wing uppersurfaces as standard for such MiGs; the stars were probably covered by the field applied dark green camouflage, so dark green bands are likely close to the wingtips;
• the wingroots were subject to strong wearing due to the boots of pilots and technicians, that usually removed the layer of paint; so it's likely to find black repaintings here.
