Griffin 1895 reverses the usual flag colours, showing a red disc on a white pennant. Rosanoski considers this an error because no other cited source supports the version.

B125 is the Burns & Laird funnel, recorded on one vessel operating in those colours; Harnack 1938 describes it as a recent change. A 1959 letter from John S. Styring instead says that the illustrated funnel had been altered in 1946. Harnack’s later working note specifies red with a black top and no white band, suggesting an error in the 1959 edition.

The P&O short-sea passenger funnel scheme dates from 1973. Marinart reports it on some ships, with others possibly adopting it in 1976. Rosanoski suggests surveys and repainting as the explanation and assumes, without source confirmation, that the company flag still applied.
