Dutch & German Coaster Fleets describes a black-topped funnel with a black HD monogram. The FOTW flag follows Brown 1995. Rosanoski regards the HD monogram as an early Karl Heinrich Danz device, probably Heinrich Danz rather than initials for the later partners. An old funnel drawing places separate black H and D letters diagonally within a white diamond, unlike the merged letters in the flag.
D414 follows Flaggen und Schornsteine 1957, although its letter proportions do not exactly match the book. Rosanoski cannot reconcile the initials in that source or the D415 livery.
Precise monogram rendering, shades and exclusive company use remain qualified.
