The original funnel is identified by TheShipsList. Nüsse’s table flag indicates dark sky blue; a sunlit example looks lighter. Although the later website photograph can look rectangular, the very pale greenish background within the swallowtail remains visible.
Brown 1951 assigns O4 to steamships and O3 to motorships; Harnack distinguishes black and grey hulls respectively. TheShipsList describes a broad red band on O4. O3 was adopted in the 1930s in pale yellow, while Jordan calls both O3 and O119 yellow. The flag was known as the “bone and billet”, or “bone and biscuit”. Early sources show O118’s flag flying aft on a funnel assigned to grey-hulled ships, although Talbot-Booth also assigns O3 to grey hulls. Black Watch confirms O3; a starboard view of Breñas shows a mirrored emblem with its tail aft. Jordan records O119 as an alternative.
