The original flag was blue with a yellow saltire and yellow RWMCo. lettering in the respective quarters; Flotilla Australia shows a royal-blue ground. The livery was also recorded for Miller Steamship. The NJK portrayal of Millers McArthur in October 1964 gives a black funnel letter, and Rosanoski considers the letter in a black-and-white photograph of William McArthur darker than the blue funnel base, indeed black. He rejects Mitchell’s shallow V in the M on the evidence of that photograph.
The later flag added an ampersand. The livery was first used by Amanda Miller. Mitchell’s shallow-V M occurs in this funnel version too and is subject to the same photographic objection.
