The unusual Swedish livery is linked by Bryggan to Esso Stockholm, but photographs of that ship and Esso Gothenburg show only the normal group funnel and no readable flags. Rosanoski cannot establish its origin. The black rather than blue ring may result from scanning; the other located company flag source is a cap badge with the ordinary group flag. The source dates transfer to Dansk Esso variously to 1970 and 1971.
Keep the explicit scope label independent; no alias or company identity is inferred.
