Sources vary the basic design. Rosanoski describes versions in which strips of the blue field separate two red triangles from a black hoist triangle, giving all three equal blue borders. Talbot-Booth 1937 is the only source he found without an “A” on the black triangle. The Merchant Ships accounts say that some vessels displayed a white “A” on the black part of the flag panel on the white funnel band, but make no corresponding statement about the actual flag.
John Inman supplies a different scheme from a photograph and drawing: a swallowtail with white borders at the top, bottom and hoist and a white saltire. The hoist triangle is blue with a white “A”; the upper and lower triangles are red.
