O.T. REDERIERNA.

O278 is documented in Brown 1982.

Collectors Corner assigns a cap-badge flag with a yellow field to OT Shipping, recorded elsewhere as O15.

O.T. Rederierna belonged to Johansson Brothers and was included in the 1982 bankruptcy. Rosanoski believes it may have continued as OT Shipping under Shipinvest and notes an apparent OT Africa Line connection.
