Very nice job.
I am different (in so many ways) in that I like the pilot/engineering models that have no paint at all. You can see all of the brass and pot metal added-on parts.
Years ago I found a non-painted engineering model of an MTH Premier GS-4 at Cal Stewart Nor-Cal and brought it home. After installing a motor and a Cruise Commander, it joined my roster as a very unique looking model.
