WIJSMULLER.

W215’s livery is supported by a monochrome photograph of Amsterdam, whose funnel base looks lighter blue. Jarig Bakker is credited for the FOTW flag.

Loughran dates the change from W177 to W179 to about 1976, followed roughly two years later by W178. The device is a chain link.

The placement of W355 in the sequence is unclear. Rosanoski considers it theoretically later than Loughran’s 1979 account, although its funnel resembles the original with a wider version indicated. Mitchell’s newer logo differs slightly.

Jarig Bakker’s W180 flag follows Brown 1995 with a darker blue.

Titan’s funnel while its hull still bore GOEDKOOP is presumed an earlier Bureau Wijsmuller version. The symbol’s ball may be dark blue, but the colour is unclear. Mitchell’s square rendering, treated as the W358 flag with a different letter colour, could instead be a funnel panel.

Titan’s photograph of 20 May 2000 is labelled old colours, presumed to mean before Svitzer. Rosanoski identifies it as W357 and notes that, compared with W356, the hull wording has become WIJSMULLER.
