NEDERLANDSCHE STOOMVAART MAATSCHAPPIJ "OCEAN" N.V.

The company originally used Alfred Holt’s livery. Several sources, including Handboek 1917, Kantoorvlaggen 1919, Brown 1943 and Scheepsbouw en Scheepvaart, show blue letters.

Rosanoski assumes dark-blue shades from the Holt connection and similarity of design. An Alcinous photograph seems to support the funnel colour, although the accompanying account may concern a pair of ships, one British-flagged under Holt. Brown 1951 shows blue letters with dots; the Flags & Funnels scrapbook has blue letters without dots.
