Being 1942 do you think the star roundel on top of the wing would be in the blue, white and red or the more familiar USAAF wartime blue roundel with white star?
If I remember correctly the change was 'officially' instituted mid-year...but there would likely have been less urgency for non-combat units to make the change. Still, by the fall of that year it would almost certainly be the white star roundel with any red centers painted over.
