Here's a link to a photo file of images of the cockpit area of a preserved MiG-3 wreck; some careful study of the remains may be helpful in determining something more detailed beyond simply applying A-14 to the whole thing:

Thanks, John. I've looked at the pictures, but I'm afraid I'm not able to make much of them. I've also looked through the pictures of restored/replicated a/c at Massimo's MiG-3 section. The Aviarestoration rebuild seems to have the tubular framework and some equipment in gray (A-14?) and the interior skin surface in some sort of blue-gray. I'm afraid it's impossible to get an accurate idea of the latter color from the photographs, excellent though they are, because it appears really different in different shots, varying from a medium blue-green to a light powder blue (seemingly similar to the to exterior under surface color). In any case, the interior skin seems to be done in something other than A-14.
