This is an amaging group and extremly rare. In this completness I know only 2 more groups.
This is the 14th known award of the Ehrenbecher für erfolgreiche Angriffe aus der Luft and the the 9th exisiting Ehrenbecher. Beside this 9 Ehrenbecher there are 2 bronce figures known that were awarded as a replacement for the Ehrenbecher.
Correct me if I'm wrong.
Herrmann Schulze served under Hauptmann Hans Masius on (Z VI), LZ 35, LZ 72, LZ 87 and LZ 107. Masius received the Ehrenbecher as well but for another achivement as an Wachoffizier on Z XI (Antwerpen on 24. Aug. 1914).
I don't have him on the crew of Z VI but he obviously was on the crew.
He started prewar service at the Luftschiffertruppe. He was part of the crew of Z VI before outbreak of war under Hans Masius. and later under Hauptmann Kleinschmidt.
