The funnel bands are called silver and blue by Merchant Ships, grey and blue in LJC, and grey or silver in Ships & the Sea. Rosanoski considers the pale band white in a photograph of Northern Coasters’ Sea Kestrel. Talbot-Booth 1944 shows a blue pennant with a white orle; Brown 1951 and Stewart 1963 extend the white to the hoist, with Brown making it thicker. Stewart attributes the livery to Firth Shipping. Rosanoski cannot say whether these differences reflect actual changes or artistic variation.

Jorge Candeias describes a triangular flag with a horizontal lower edge, purplish blue with a dark-blue border except at the hoist. Rosanoski observes that the illustrated field is only very lightly tinged blue.

The company website shows a mauve field and very dark blue border except at the hoist, separated by white fimbriation. Although the image suggests a right-angled triangle, Rosanoski thinks an ordinary long pennant may be intended, consistent with earlier flags. The field is recorded as mauve but looks grey to him.
