ARMEMENT DEPPE S.A.

The flag is white with a broad blue border, one-fifth of the flag height in the Larousse description, and a red rosette between blue “A” and “D” letters. The FOTW illustration has a yellow centre. Stewart 1957 gives red petals, a yellow core and a black centre; Stewart 1963 omits the black centre, while US Navy shows pale blue. The funnel is yellow. A painting of Euphrates supports the livery, although its flag centre cannot be resolved. Rosanoski regards this as the original flag, while noting uncertainty about whether later portrayals represent an actual change.

Brown 1934 replaces the flower with a red, yellow and black target, serrated around the outer red edge. Talbot-Booth uses this form through 1949; FOTW labels it a reported 1934–1949 variant. Rosanoski allows that it may merely be a different rendering, since other sources continue to show the rosette.

Brown 1951 and 1958 show a roundel without serrations; Brown 1958 uses white in place of yellow, probably a printing error. The roundel flags remain suspect against the consistent earlier rosette evidence. Some funnels had black tops, indicated in Jordan and Merchant Ships text. Black-and-white photographs of Mar del Plata and Mobeka confirm the A137 funnel; Mitchell calls it Deppe Line.
