Bituma was on long-term Johnson charter from 1986, but these are not Johnson colours and may belong to a sub-charterer. Port and starboard photographs show a green winged dragon with a tail, breathing yellow flame, facing forward on both sides; something red appears at bottom left. Mitchell’s related drawing under Knut Lundgren appears to include an oil drop and differs in colour. The narrative calls the design T445, while the approved image is U313.
