This aircraft is the only MiG-3 fitted with the AM-38 engine in factory in August 1941. This engine gave higher power but less altitude capability than the AM-35A. The aircraft had a significant improvement in its low-altitude performance, and outclassed even the Bf-109F. The trials showed the necessity to redesign the oil and water radiators because of the higher heat generation of the new engine, and as well, the Il-2 program was prioritary for the use of the AM-38 engine. Because of these factors, the program was halted.
A pair of other MiG-3s were re-engined in such  way in operative units.

The characteristics look to be:

• late type with slats;
• a small pipe on the left side, collecting inert exhast from the 2nd and 3rd stacks of the exhaust pipes for anti-flame inert gas system of the fuel tanks;
• exhaust pipes similar (if not identical) to the series examples; the aircraft carried two different configurations for exhaust stacks, I don't know if this is the early or the late one;
• green and dark green camouflage;
• slightly oblique fuselage star, with black outline;
• particularly large stars under the wings;
• a (probably) red band on the top of the fin;
• "95" roughly painted (or drawn with chalk) on the fin;
• propeller blades with aluminium forward surface and black rear surface.

This plan view is hypothetical, based on the similarity of the profile camo scheme with the example "white 04".
