Hard to watch, but I got the idea via multiple fast forwards. Never heard of K-color - will give it a shot.
I knew that Atlas did the Milwaukee paint scheme, but the only photos I have seen is without the corrugated stainless. I asked them if they had done a "stick-on" for it, but no reply.
And I think I found who did the model in the photo - they specialize in Milwaukee decals. More when they e-mail me. Edit: Streamstyle Graphics. They actually etched the corrugations in nickel silver. HO only.
