Hey, good work JKim!
The cockpit color was A-14 "grey". I have the Akan colors, and its a mid to darker grey. Sometimes people use a blue color, that is not correct. The very early MiG-3s had a "silver" color on their cockpit. This was done for a high protection against UV light. In 1940 / 1941, the use of A-14 was ordered, for all interior coloring. Wheelbay was pre war "light blue" undersurface color, landing gear was A-14 grey or undersurface color, depending on the batch delivered sub componements. Wheel disk is probably 4bo green (a dark green with a hemp / yellowish glow in it).
HTH,
Remco
