House flags of trawler companies

Sources on the house flags of trawler companies are very few and far between. The only one I know of is the 1911 edition of Olsen's Fishermen's Nautical Almanack, which had small pictures of some flags in the page margins.

Vessels Carrying Inflammable Liquid

image by Miles Li, 24 October 2009

In many jurisdictions historically under the British Empire, vessels carrying a cargo of inflammable liquid (i.e. tankers) are 'traditionally' required to fly a red square flag with a white central disc while in port during daylight (and a red light at night). The exact specifications are up to individual port authorities, but typically the flag should be no less than three feet (90 cm) each side, with the disc no less than six inches (15 cm) diameter; except for small inshore vessels, which may instead display on a tall pole a metal 'flag' no less than one-and-a-half feet (45 cm) each side, with the disc no less than six inches (15 cm) diameter.
In practice the metal version is by far the more common, since most vessels with a proper yardarm would simply fly the International Signal Flag 'B', or even a plain red rectangular flag for that matter.
