The flag derives from Pacific Coast Steamship’s red cross on a white lozenge, adding four white admiral’s stars on a blue field. A timetable confirms the format, although other sources vary its proportions. The funnel’s lifebelt-like ring reads THE ADMIRAL LINE above and PSSC upright below. Brown 1943 places the flag on the yellow funnel within a white ring; a black-and-white H.F. Alexander photograph does not clearly show the ring.
Talbot-Booth and Rimmington use a narrower cross, perhaps intended as cross paty but appearing closer to a cross couped. Jordan does not detail the funnel emblem.
