Rudolf Klimke, Jasta 27, Wia (shoulder) or Ltn Schmitt, Jasta 27, Wia (knee); claims were made by May (Fokker DVII out of control) and Lt G R Knight (Fokker DVII crashed)
Ltn.d.R. Hilmar Quittenbaum was KIA over Arleux-Douai on 15 September 1918; I have this as being by 1st Lt T L Moore, 148 USAS (Fokker DVII crashed (?) 18:45 south-west of Arleux).
At the moment I have no other matches for May's claims.
