Most sources show or suggest white lightning flashes, though their detail is unclear. Lloyds 1912’s A24 version shows a black shield.

The Flag Bulletin reproduces what Rosanoski takes to be an actual flag in proportions 3:2, with a deeper fork extending one-third of its length.

Cableships & Submarine Cables dates A641 to 1873–1908 and A640 to 1908–1967. In both, the shield is black and the lightning flash yellow. The upper stars, as far as the swallowtail point, angle towards the upper fly. The accompanying funnels are assumed, not independently established.
