Documented shared associations — Burmah Oil / Burmah Oil Tankers — documented petrol-pump livery

The later livery is described as the “petrol-pump” sign. The white flag bears a red-white-blue triband panel with pointed top and bottom edges and black “Burmah” on the white band. Marinart gives the livery without describing the sign; Ocean Ships specifies only the panel colours. B491 is recorded for Burmah Endeavour, delivered in 1977 and chartered to Exxon in 1978, with other fleet use apparently earlier according to Marinart.
