reynoldsno1 I think pubsman is referring to the one wing balck, one wing white of 1940 vintage rather than the "Invasion Stripes of 6th June 1944 vintage.
I vaguely remember that it was for ID purposes, as were the invasion stripes and the red noses of the 56th Group P-47's. Basically to try to give the Pongo's and the Snotty's a bit of a clue that it was a friendly aircraft flying over them.
