Red and blue bands recur throughout the group, usually with a white company initial. The colours are said to represent early metal cargoes and the Gota Alv; another story attributes the first flag to a red-and-blue striped skirt belonging to Axel’s wife. Loughran’s discussion concerns Tirfing and related group markings. Some earlier books instead assign Ferm’s F177/F179 livery to Axel Broström & Son.
No flag is given specifically for B531; Rosanoski assumes the group flag applies.
B48 may be a website logo reproduced as a flag rather than a design actually flown. Rosanoski initially questioned whether the full-lettered logo flag was intended for shore advertising.
The 2000 graphics combined the traditional Broström flag with Vopak’s green. Nüsse’s flag places the full logo and “BROSTRÖM” on a broad white horizontal band between narrow blue bands. Bro Alexandre photographs show a dark-blue funnel with a dark-grey, possibly black top; later photographs confirm the blue despite misleading lighting. Bro Grace photographed in June 2005 confirms that the full flag was flown at sea, resolving Rosanoski’s earlier doubt for this version.
B611 follows chartered Vega Spirit in January 2006, with a further Seto Eagle report. Seto Eagle belonged under the former Iver Ships operation; an Iver connection for the chartered vessels is presumed.
