The skipet depiction of B376 makes the blue flag bands wider than the white. Rosanoski takes this flag to accompany that source’s B378 cruise-ship funnel. The same source shows two black funnels with three white bands; the motor-ship version doubles the white-band width and reduces the black gaps.
B379 is a red burgee with blue upper and lower borders, two white bands and white “BDS” above a white star on the red field. Some published illustrations place the letters in a straight row. The associated funnel is black with three white bands.
Loughran says the letters were always arched, making the straight-letter B379 and B378 depictions incorrect. B377 is described as the original flag, although Griffin’s earlier publication of B376 makes the sequence confusing; the arch in Lloyds’ B377 is barely discernible. Jan Oskar Engene found arched letters in photographs of actual flags and suggested that straight lettering came from printed logos showing a waving flag, rather than proving a real variant.
Ridley Tugs adopted the B377 funnel as its final version, having varied its funnels with important contracts.
Meteor and Venus are described with an orange funnel, while skipet calls this cruise-ship version buff. A Collectors Corner cap badge colours the flag’s letters and star yellow with white edging, unsupported elsewhere. Engene’s account gives a black funnel with three white rings, later changed to yellow with three white rings, tentatively in the 1960s.
B785, with a waving flag painted on the funnel, is assigned to ships on the England route from 1966 to 1975.
