Do you have photo evidence of the yellow outlined roundel on the top wing United?
As it's supposed to be a June 44 bird, everything I know tells me it should be just the plane blue and red upper wing roundel. No yellow outline or white inner ring as those didn't show until the very end of the war, well intol 1945.
The wing D-Day stripes seem to be missing a white stripe as well and look too narrow overall for the wing.
