The flag is blue with a white diamond not reaching the edges and a red star. A company advertisement confirms this version. Larousse depicts the funnel marking as a panel; Brown’s 1926 and 1929 panels have a diamond extending throughout, as does Talbot-Booth’s later funnel band. Larousse’s 1930 flag still has an inset diamond.
Talbot-Booth’s notes state that the flag diamond had been enlarged to the field’s edges, yet the older illustration continued, and the 1944 text says the livery remained unchanged through the name changes. Rosanoski nevertheless considers a change plausible because Stewart’s 1950s editions and Brown 1982 show the larger diamond. Dominique Cureau suggests the 1927 SAGA takeover as a possible cause.
