The flag is a blue swallowtail with an ornate yellow-and-black double-rope border except at the hoist. A yellow-and-black angled zigzag flash accompanies white WTC in the lower fly, with a taller T.

Brown 1943 removes the border and changes the letters to WTCo. This differs despite Talbot-Booth’s account that Cable & Wireless flags replaced the constituent-company flags in 1939.

Michael Wilson’s FOTW W449 squares the border divisions like two rows of bricks instead of angling them as rope. W450 reuses the earlier flag’s flash, which Rosanoski considers probably correct, although Brown 1943 depicts a variant.
