Alright so the original gloss back then was probably somewhere between today's gloss and Semi-Gloss paints?
The suede finish isn't just a smooth flat color, it has a texture to it?
Eastwood has a black textured powder coat it isn't as rough as black wrinkle paint. I wonder how close that would be to the suede finish. Take a look at the picture of the diamond plate, is that to rough for the factory swede finish?
