Sources differ over white or silver funnel details. The 1975 coastal book gives white for the tug fleet and silver for London’s effluent tankers; Coastal Ships 1967 also gives silver for effluent tankers, but ABC British Tugs 1960 gives silver for tugs. Brown separates the funnel bands by their own width and draws a different K. Rosanoski bases the image on a black-and-white photograph of Keston.
