Swedish Gulf Line AB — historical sourced livery variants

The apparently earlier flag was white with a squarish blue S, supported by a cap badge. Frances Salman’s monochrome photograph is taken to show the early funnel, though its band marking is indistinct. David Salman’s photograph shows a black funnel with a white band and no visible charge, together with a white foremast flag; Rosanoski therefore considers it evidence for S660 rather than the later livery displayed alongside it.

The yellow flag dates from at least 1976, when Sea Breezes described the colours by association rather than giving a full description. Its red was noted as unusual among otherwise similar Swedish company designs. A second cap badge supports this later flag. The Bryggan illustration is associated with David Salman, but the photograph does not support that attribution.

No asserted takeover/rename; S660 reconstructed funnel and S659 exact early use dates remain qualified.
