Hi Thorsten
I dont think that Krefft ever was a member of any AFA. Instead he did join
FFA 5b (Bavarian) already on 26 Feb 15. He stayed within this unit until 12 Oct 16 (except for a short break) when he was posted to Jasta 11...
It is possible that FFA 5b did use artillery a/c during his service there. It is also a possibility that Reinhard etc do have some hints about the markings of this unit...??
