The chequered flag, apparently following Stewart 1963, differs from US Navy’s blue flag with a gold cross interrupted by blue at the centre, creating unequal compartments. Rosanoski finds different parent/subsidiary flags unlikely but cannot resolve the discrepancy: the Swiss-ships illustration follows US Navy without specifying dates or subsidiary use. Mitchell’s S349 funnel appears based on Blue Ocean during 1984–1985, later than the marking’s apparent period.
Bernina’s photograph supplies what appears to be the standard funnel when not in charterers’ colours. The initial relates to Baron H.H. Thyssen-Bronemisza; Bernina was owned by St. Gotthard Schiffahrts. Mitchell assigns the funnel to Swiss Overseas Navigation Corporation.
During the Baron’s ownership the flag, according to Swiss-ships, was red with a blue triangle extending throughout from the fly, bearing a grey dolphin swimming towards the fly.
