MELBOURNE STEAMSHIP CO. LTD.

The white and red bands are described as broad, with dark blue. The flag combines earlier Black Eagle and Norton, Graham & Co. flags. The Log gives MSCo, with blue M and Co and a slightly larger white S; the o is not enlarged. A mid-1930s menu and possibly an actual flag instead show all-blue lettering. Marine News shows equal-height black letters and an enlarged o, but its monochrome hatching and lack of colour specification make the black uncertain. Earlier Williams and Lonsdale drawings also show very broad funnel bands.

York Syme used M437 in 1961, with Melbourne Steamship half-owning and presumably managing the tug.

Dignan’s Sampson-based flag shows a blue S, while the underlying monochrome source does not establish that colour.
