The shell trademark derived from Marcus Samuel & Co.’s shell-import trade. Loughran describes the early livery as an alteration of the Shell Transport & Trading and Marcus Samuel colours after Anglo-Saxon’s formation, although LJC 1909 shows the Shell Transport & Trading livery. Loughran dates replacement of A341 by the scallop-shell flag to 1932; M.J. Pryce instead gives A341’s use as 1907–1945. Rosanoski notes that Talbot-Booth already shows the shell flag in 1942. A341 is also attributed to British Imperial Oil Co. in Log. The Lloyds 1912 flag has a broader saltire than the Larousse Commercial Illustré version used for the FOTW illustration.
The shell livery was shared with other group companies: Brown 1943 assigns it to Nederlandsch-Indische Tank Stoomboot Maats. World Tanker Fleets says Anglo-Saxon ships adopted it when repainted after the Second World War. Mitchell renders the yellow funnel as buff. Merchant Ships dates addition of the funnel emblem to 1945–46, before the reported 1953 name change; a photograph of Circe Shell shows a narrow black top. Harnack 1949 shows the later Shell livery referenced as S569.
