Hi Dave
I am very interested to possible have a copy of the map...!
Flieger(Fokker?) Forell was what we usually call a KEK(a non-official unit with attached fighter pilots from flying units in the area).
The unit do also have the name Parkzug der FA 37 in one source, but this is probably a misinterpretion..but it indicates that most pilots did belong(home unit) to FA 37..
It was establish on 13 May 1917 and was later dissolved on 13 Sep 1917..
Perhaps I can translate some of these terms into English, but I hope some German first will try..
I am also interested in the Flak units and balloon units stationed in the area..
As an answer to a recent thread here on the Forum, it would be interesting if the commander of FA 22 is noted on the map..?
