Schneider’s account of a poster in Hamburgmuseum describes quarters of green at the upper hoist, red at the lower fly and white, overlaid by a full-height white oval edged green and containing a green capital B. The ships had yellow funnels with black tops. He understood the company to have run a Hamburg–Nordeney–Borkum–Helgoland mail service early in the twentieth century.
Mathies’s black-and-white illustration differs from the museum poster. Assuming conventional heraldic hatching, Rosanoski reads the B as blue and the oval as a ring. The ring appears black, but the small illustration could not show a colour hatching clearly; Mathies provides no hatching key.
Lloyds 1904 gives Nordseelinie diagonal green and red quarters with a white oval bearing a red representation of the Hamburg castle.
