Caltex 1959 shows a yellow swallowtail with a blue Scandinavian-style cross, reproduced as D455. D456 is rectangular and has no stated source. Rosanoski questions it because Oram’s statement that the website flag was correct apparently referred to the earlier swallowtail, not a new rectangular design.

Rosanoski also questions the offset cross in Caltex. US Navy 1961 places the centre of a slightly narrower cross halfway between hoist and fork. Flag images on an ashtray and cufflinks support this arrangement, though the fork may be shallower.

Berea’s September 1973 photograph supplies the funnel. The top is rendered black, although it might appear very dark blue in the photograph.
