From 1964 Mobil lettering took precedence over Pegasus on some funnels, gradually spreading, although Sylvan Arrow still carried Pegasus alone in February 1965. The flag did not change. Loughran places the shield frame inside the white shield. The livery also appears for Iberian Tankers, Kurze Marine and Kurz Tankers.
