Deutsches Reich Kaiserliche Marine, Reichskriegsflagge (1919-1921) Fahne, Flagge 90 x 150 cm, Like the former Ensign, except that the black-white-red in the canton is replaced by the black-red-gold —the Iron Cross remaining— and the Prussian royal eagle in the round center field is replaced by a new republican eagle, essentially the old eagle without the crown, orb or scepter and with no escutcheon. Ratio 3:5. This was replaced in 1921. (FOTW).
The first new war ensign should be introduced with the decree of 27 September 1919; however, this flag was never used, although samples were produced. The design was based on the previous war ensign, only replacing the eagle and the black-white-red canton with a black-red-gold canton.
