EGON OLDENDORFF OHG.

Sources vary in the size of the flag lettering. Rosanoski doubts O10’s funnel because Jordan records O9 before the Second World War. Mitchell shows a white band on O9, which Rosanoski attributes to differences in funnel height.

Both flag and funnel were confirmed on Margaret Oldendorff at Wellington on 4 October 2000. Nüsse’s later table-flag photograph gives a better blue than his earlier website image.
