Merchant Ships 1942 and 1944 give B515 as an alternative funnel of the Stavanger company Sigval Bergesen. Rosanoski regards this and the combined fleet’s flag attribution as confusion between the two companies.
Jordan describes a white funnel with black top, diagonal light-green stripe and house flag, but the arrangement is unclear. A monochrome photograph of Charles Racine appears to show the flag on a lighter band within a very deep black top.
The house flag is a white swallowtail, described as 3:4, with a green diagonal stripe and a black monogram combining “B” and half an anchor. Sources differ on stripe width: Brown 1958 is widest and Stewart narrowest. Except in Stewart, it touches the lower hoist corner. Rosanoski gives a consistent angle of 40 degrees, with the stripe’s upper intersection varying by width and its sinister edge generally halfway along. B85 follows Nüsse’s flag. Two Collectors Corner cap flags differ in green shade and the “B” position relative to the bendlet and fly. The livery survived the 1986 name change.
A rectangular flag was added to FOTW in December 2013 on the reading that Nüsse showed a rectangle while the former company logo showed a swallowtail. Rosanoski rejected that interpretation in March 2014: the faint background concealed the swallowtail, which remained discernible. Rob Raeside acknowledged the transparency problem and proposed a correction. Peter Hans van den Muijzenberg’s commentary notes that the funnel flag reverses on the starboard side to fly from stem to stern, while the anchor-B remains in obverse. The funnel’s swallowtail tapers, but he is uncertain whether actual flags did so; he also suggests light-green areas might indicate gaps rather than fabric.
B604 follows the company website. Havsol on 13 January 2001 shows its funnel and a flag panel whose green stripe meets the upper and lower edges rather than the corners used by other sources. The flag is indistinct but appears consistent with the website. Berge Boston on 12 July 2005 and a portside view of Berge Nice, listed under The Green Tankers, provide further funnel confirmation.
