HERMANN BUSS GMBH & CIE.

The source numbers three flag forms without explicitly pairing those numbers with image IDs. Version 1 is a horizontal black-red-blue triband with white HB overall; its funnel is buff with a black top and the flag flying from a pole. Version 2 is white with an intertwined white H edged blue and a larger blue B, flanked by black-red-blue triband panels. Its white, black-topped funnel carries intertwined white H and larger blue B, with a black-red-blue triband extending forward only. Version 3 has a narrow horizontal black-red-blue triband interrupted at the centre by the same intertwined letters, separated from the band by the white field.
