The earlier flag was blue with a white “B” alone. Brown 1958 also assigns this livery to Transoceanica Genovese and Unione Ligure Armamento without explanation.
The later flag is blue with a central white “B” flanked by two white stars. It also appears in connection with Gruppo Carboflotta, including Carbofin and Carbonor, and Carlo Canepa of Carbocoke was observed with the B10 funnel in October 1965. Sache’s rendering angled the stars, apparently through interpretation of a fluttering flag image; Rosanoski says regular sources show them upright. The suggestion that “B” represents a founder or former owner is explicitly an assumption in the FOTW account.
