The funnel colours are assumed from the flag. Brown and Mitchell connect the livery with OT Africa Line, an associate of O.T. Rederierna whose exact relationship is unclear. A Collectors Corner cap badge assigns the flag to O.T. Rederierna, suggesting it originated there.
Rosanoski presumes that the 1982 reorganisation turned O.T. Rederierna into OT Shipping at the same address. It managed for Concordia Maritime, Shipinvest, Stena and United Tankers. His later comment suggests disappearance by the end of the decade, although the register notes include 1992–93.
