Here the series data are interrupted, and the next matrices have unknown date of recording, attributed by others to 1918.
So if this was recorded and released during or after the war, the ties between Gramophone and Deutsche Grammophon were already cut, and probably this label is one of the German label versions done after the injunction which forbid the use of the common nipper label for the German company outside Germany. The trick here is to omit the Nipper from the forbidden trade mark.
