REEDERIJ GEBROEDERS GOEDKOOP.

The earlier markings are described with tug fleet numbers on the funnel band. Albert Goedkoop is photographed with this funnel in the 1960s, but most vessels show plain bands, sometimes narrow and never as broad as the Maritime News illustration; Rosanoski adjusted his band to the photographs. Pieter Goedkoop instead carries its number on the white bridge. He doubts that the numbered funnel was ever used with the accompanying flag, since early photographs show the G392 flag and unnumbered funnels. Later tugs had uptakes rather than funnels.

Winston Churchill, built in 1946, documents the funnel; Prins Hendrik, owned in 1910–20, establishes early use of the flag. Hermina E. Goedkoop shows the complete livery and an indistinct bow pennant, possibly white with a narrow horizontal band and an overall G. The flag still flew over Wijsmuller’s port office in 1992, and a pennant form survived until 1998.

The original sailing-vessel flag is based on a small black-and-white picture of Alida. Rosanoski reads its stars as five-pointed and angled towards the upper hoist.
