According to "A Legacy of Speed The Gee Bee Racers" By Mendenhall/Murphy the R6/QED was built for Jackie Cochran and painted "lucky Strike green" since she was there spokes model. It was meant to race from London to Melbourn in the Mac Robertson air race. She flew it a little then it was sold to Charles Babb. He repainted it white with a green stripe. Later (1938) he added 61 to the side and right wing tip bottom for racing (not sure of the numbers color). Then Babb sold it to Capt. DA Francisco Sarabia who painted it "gleaming high-gloss white" with red speed lines (stripes) on the sides along with the script also he added the cowl art work (crossed American and Mexican flags).
