The pic of the B17 is not a Coastal Command scheme, which was Gret/White. It's in a camouflage scheme destined for the RAF, but never used, as it was presumably transferred to the USAAC as mentioned. The few B17Es with the RAF were with Coastal Command, in the scheme mentioned above, whereas the (equivalent colours) of darl green, dark earth and Azure had been used on the 90 sqn B17Cs, the remaining few then being transferred to coastal Command and re-painted.
