Nüsse’s flag was initially interpreted as blue and black, but a 2004 photograph of Zenit shows a funnel panel with two shades of blue. Mitchell omits the lines below the panel and makes its field white; Rosanoski suggests either a later addition of the lines or a distant view in which the pale blue was not discerned. A 2011 photograph of Coneste shows the flag panel on the superstructure rather than the black funnel, suggesting to Rosanoski that the vessel may have been chartered out.
