Mobil Fuel first wore the 1957 livery. A stylised wing-like device below Pegasus is interpreted as a heavily stylised V, a surviving reference to Vacuum. McMillan’s US Navy-based flag has a deep fork, whereas an actual flag photographed for Rosanoski has a shallow one. Mobil Apex confirms the funnel; Tatarrax also has blue below the white band, while Mobil Meridian, Mobil Power and Mobiloil omit blue. US Navy turns the funnel Pegasus aft.
