Thanks all for the quick replies and pictures!!! Bare metal it is! I agree even if painted it probably wore pretty quickly. I loved the shot of it folded up because it showed the screws along each side which I can add!
I ordered some AK Interactive Metal Paints for this beast, the Vallego Aluminum does not look right to me. And the Model Master Aluminum both the Acrylic and the Enamel seem wrong as well. So I ordered Duraluminum, Dull Aluminum, and White Aluminum to try. I am speaking about the overall aircraft color here.
I also noticed in all the pictures you all have kindly supplied to me as well as what I could find on the net, the color was not consistent across the entire aircraft but typically varied panel to panel slightly with some looking very dull almost washed out, and others very bright.
