Bideford was reported with a black funnel in May 1964, later amended to blue for the jointly owned Blandford. The banner was more rectangular, with the letter touching the spears and no spears visible behind it. Rosanoski presumes a dark blue.
B917 uses Mitchell’s lighter blue. Mitchell also colours the narrow diagonal panel line blue, whereas US Navy makes it black.
The Skipet source indicates a base colour similar to Fred Olsen’s funnels, without dating the change.
