HANIEL.

The house flag is a plain horizontal green-white-black tricolour in the recorded flag references. A black-and-white photograph of Franz Haniel XXIII around 1913 appears to show it at the foremast, though the colours and identity must be assumed from that view. A handwritten note in the US Navy source limits the flag to barges, with seagoing ships using Oldenburg-Portugiesische’s flag. Rosanoski notes plain black funnels on the Elbe vessels and tentatively suggests Tazacorte as a late user of the flag. Schneider nevertheless observed a Haniel flag on a Haren vessel at Hamburg on 26 April 2007, after Imperial’s takeover. His suggestion that Imperial used former companies’ flags is based on observation rather than a documented general rule.

The funnel has a broad white band carrying the flag across its full width. The flag itself is not separately given and is assumed to apply.
