The Sunderland is one of my favorite flying boats. There is something about the Flying Porcupine that just makes me go cool. I even got a chance to see one at Fantasy of Flight during the Nationals even though it had been converted to a passenger version.
This new sheet by Aviaeology covers markings for 3 of the Mk.III versions as operated by the RCAF in Coastal Command. All 3 aircraft scored U-boat kills. They all wear similar schemes of white fuselage sides and undersides and either Dark Slate Grey and Extra Dark Sea Grey upper camos or the later version with just Extra Dark Sea Grey. The instruction sheet is in black and white and gives profiles and upper views of all 3 aircraft.
