Help with Black AWM -3-11 Holster

[George Anderson]

Before I spend any more time on this, is the second guy's name Fiehler or Kiehler? You spell it both ways. So far neither of these nor Scharnagl show up in the Bavarian Army's Rangliste of 1914 or in the Ehernliste 1914-1918. Whoever he was he may have been an officer of the reserve in which case it becomes much more difficult to track.
