The flag is white with two horizontal red stripes and a black “W” superimposed on “B”. Schneider describes the B as twice the width of the W; Rosanoski observes that the cited 1956 source instead uses similarly designed letters with mixed thick and thin strokes, as in B783.

US Navy 1961 shows narrow red flag bands and larger, thicker black letters. Its funnel bands follow the illustrated style. The Mitchell funnel is indistinct, but the B appears to fit within the width of the W rather than extend beyond it.

The version used when acting as corresponding shipowner for Partenreederei has a white flag with red stripes along the top and bottom. At the centre are two vertically arranged, broken black rings and two horizontally arranged, complete red rings. Rosanoski places the black rings over the red ones, with the upper ring’s break on the dexter side towards the hoist and the lower break on the upper sinister side towards the upper fly; none touches at the centre. Mitchell’s funnel differs: the red rings touch, the black rings nestle outside them and the rings do not overlap.
