Old Dagger - maybe German

I am trying to ID this old dagger. It has a German inscription and a
German designer. It has four etched flags, two on the top appear to
be composites and the two on the bottom are Turkey and Bulgaria. The
top right flag has an iron cross centered in the upper right
quadrant. I have no clue regarding the age. This may predate WW 1.
It has a black, plain metal sheath. It is sharp and is about 11"
overall.

Any information regarding the year and what this knife might be
celebrating would be helpful.
