Trim painting on the Narrow gauge.

Does anyone know off hand what was standard D&RGW practice for painting a Narrow Gauge 2-8-0 around the early to mid 1940's?

I'm currently rebuilding a Bachmann Large Scale 2-8-0 to resemble an Ex-crystal river engine (its numbered 370, as it has no true prototype, just a freelance idea) and was planning on going all the way on it. Inculding a complete repainting of the locomotive. So I was wondering what standard practice would be in the 1940's. What Mixture was used on the smokebox, what color was used on the trim on the running boards and cylinder caps. Basically, how would they have painted the crystal river engines in the 1940's.

And does anyone have any intersting idea's for how to rebuild the engine? I've already converted from Baker valve gear to simple stephenson, moved the bell and the sand dome around, and cut back the counterweights to reseble the simple linkage to the rods rather then actual counterweights.
