DEUTSCHE BUNDESBAHN BUNDESBAHNDIREKTION HAMBURG,

The Hamburg flag is white with a black winged inverted triangle in black, red and gold, its point between D and B. Rosanoski’s 2004 account describes black letters. Mertens’s later photographic account instead specifies red initials and long, thin wings, explaining that small originals had caused errors in the earlier drawing. Eugene Ipavec’s D443 replaced Jarig Bakker’s rendering.
