SP steam paint schemes

[Anonymous]

I have seen many builder's photos (Baldwin) of cab forwards in a two tone gray paint scheme. In the book Three Barrels of Steam there is a wonderful photo of a 4-10-2 in the same scheme. The author states the colors are "dull gray graphited smoke box and gloss gray enamled boiler jacket." Any ideas as to what commerically availablepaints may represent these? I would like to paint up an old Rivarossi cab forward, so I'm kinda partial to using the Scalecoat II paints as they are plastic compatible.
