Sources vary the G’s shape; the illustration follows the National Maritime Museum flag, dated about 1951 and measuring 1193.8 by 1803.4 mm. Mitchell records a Glasgow sighting in 1950. Talbot-Booth and Stewart contain erroneous company initials, with Talbot-Booth correcting its image caption in 1938.
