Klaus-Michael Schneider describes a white flag with two red horizontal stripes and, between them, a black W overlaid by an L twice its height. Rosanoski says the portrayal is not quite right and should be as in L461.
L461 is retained from the Esso, Flaggen & Schornsteine, US Navy and Stewart sources, with funnel evidence from Mitchell.
