The blue flag bears H.M.G. The illustration uses the ornate FOTW lettering, apparently derived from Rehm; other sources simplify the letters or omit dots. Lloyd Reedereiflaggen 1933 assigns it to both Gehrckens and Nautik.
Stewart 1963 places dots after the letters.
Schneider’s company-history-based image has minor differences in the letters.
