I believe this scheme was used on a number of diesels that were built-in the late 30's to mid 40's which included SW1's, NW1's, GE 44 tonners, Alco S2's and possibly HH660's.
Before that early diesels were black with aluminum lettering, i.e boxcabs, Macks, early EMC's and Alcos. Then this scheme then Cornell Red with 3 black stripes.
I definitely have seen photos of the 44 tonner in this scheme. It was in one volume of a series of books published by the Sayre PA historical society. I don't have it with me but I'll see if I can find other examples when I get home.
