Jerry,
Here is excerpt from a article about modeling a RN Corsair:
Fleet Air Arm aircraft were painted with a camouflage scheme of Sky on the lower surfaces, and a disruptive pattern of Extra Dark Sea Grey and Slate Grey on the upper surfaces. For all British-built aircraft and those built by Grumman, this is correct.
However, both Eastern Aircraft provider of the TBM-series Tarpon/Avenger to the FAA and Corsair manufacturer Chance-Vought used 'US equivalent colors.' These colors were: Sky Grey replacing Sky, Dark Grey replacing Extra Dark Sea Grey, and Olive Drab replacing Slate Grey.
All these paints are available in the Model Master line (enamel or acrylic) and already mentioned Techmod Corsair decals.
