Brown 1951 misplaces the illustration under Sociedade Portuguesa de Navios Tanques and omits d’Amico from its index. The white-disc emblem resembles an H whose horizontal arm extends beyond the sides, topped by a slanting roof.
Earlier website images support this flag and logo form, but with a smaller white disc. The source compares disc size and notes that Brown’s later editions centre the cross; its comparison passage uses the inconsistent reference D169.
Photographs confirm the funnel but show narrower red bands: very narrow on Mare Nostrum, somewhat wider on Mare Adriacum. The white circle also varies, appearing smaller on Scorpius.
The FOTW rendering after the Caltex book shows a yellow flag with a blue Maltese cross and blue centre disc. Rosanoski points out that the company website and most sources make the centre white.
