The initial S145 funnel lasted until the early 1870s, when S144 replaced it. Rosanoski considers S633 probably erroneous. The early flag was yellow with a blue saltire; it changed around the First World War to avoid confusion with the Russian naval ensign, presumably when the yellow faded.
The Thule takeover in 1916 brought its funnel colours, with Bryggan dating the change from S182 to S181 to that year. Cargo ships initially used the separately cited S183 funnel, but the account says all used S181 by 1938, despite Harnack continuing to illustrate both. Saga’s monochrome photograph confirms S181. Sources differ in cross shade. One published S181 flag narrows the cross to a point at its centre; Bakker’s museum-based alternative specifically rejects a Maltese cross.
