Denny,

Jeff's answer to your question is a good one.

There were no two-tone A-D RPOs until 1954 (except one green/green combination for Carryall Suburban upper/lower body in at least some early years). Even in 1954/55, there were no two-tone fender/body RPOs.

I know of no documentation to prove the availability of any specific special-order two-tone combinations in 47-53.

There is a document called the "Silver Book" that described available specially equipped truck bodies (vocational equipment). That book might have information on special order paint combinations. There is a photograph/drawing of black fenders and a colored body on a special equipment 1/2 ton truck in the 1949/50 Truck Data Book.
