The flag is red with a white H shadowed black. Wessel, Duval’s website identifies the H as honouring founder A. Hemenway, although the earlier FOTW account did not know its meaning. Talbot-Booth does not indicate shading on the funnel letter.
W479 is from a matchbook offered as a possible 1930s West Coast Line cruise-ship item. Rosanoski considers that it might instead relate to the post-war joint venture, but notes that its funnel resembles W257. He suggests, without establishing, that partners might have used their own funnels with a common flag.
W338 comes from a 1960s photograph of the chartered Istina. Rosanoski connected its funnel with a drawing attributed to West Coast Line of New Orleans and the joint service with Rederiet Ocean. Marc reported similar information from a Chilean contact in support of that identification.
W339 is a further funnel from Mitchell, with no separate written description.
