Merchant Ships 1942 records a recent change from M330, while some tugs continued using the original funnel in the C573 livery.
C574 is shown as an alternative for paddle steamers. C575’s funnel band is drawn lower than it appears in two photographs.
The later flag is quartered diagonally white at the top and blue at the hoist and fly, with counterchanged C at the top, A at the hoist, N at the fly and L at the bottom. Rosanoski subsequently questioned his original blue shade after a company cap badge was identified: it showed light blue, which he considered more reliable than interpreting a book illustration.
