 In May 1938, after Bulleid's appointment as CME, No. 749 Iseult was trialled in bright unlined light green with yellow-painted block numerals replacing the cast numberplates. The tender was given two designs of lettering, with "Southern" on one side and the initials "SR" on the other. The Board of Directors disapproved and Bulleid repainted the locomotive in darker malachite green with black and white lining (this would later be applied to his Pacifics). The legend "Southern" in block-lettering remained on the tender, though the number was relocated to the cabside on one side and the smoke deflector on the other. Both were painted in a light "sunshine yellow". No. 749 was returned to Maunsell ’ s green livery.
