DLL.

D190 has plain letters. Lloyds 1904 and 1912 show plain funnel letters but ornate flag lettering as in D189, whereas German sources use ornate lettering on both. Other sources pair D190-style flags with the D189 funnel form. A Tenedos photograph confirms a full band joining around the funnel, with part of an apparently plain L visible. Jordan instead describes black DLL letters on a red-white flag; Rosanoski regards this as erroneous because other sources give white letters on a black circle.

Several sources give this funnel to Atlas Levant-Linie while distinguishing its own flag. D189 later appears under Bock, Godeffroy, apparently from 1956. Sampson also mentions buff funnels without saying whether they were plain or carried a flag band. The livery was replaced by Hamburg Süd’s in 1967.

The FOTW rendering has thin, plain white letters on a central black disc, over a red-white diagonally quartered field. The accompanying description says DL, which Rosanoski marks as questionable. The US Navy version uses an oval rather than a circle.
