Hi Thorsten und ein Gutes neues Jahr..!
The french pilot is named
Mdl Henri Durrant KIA in the German monthly list of captured aircraft.
Udet with his Jasta 37 was serving in Flanders so we can probably exclude him as responsible...
Also the excellent book about Jasta 32 by Jörg Mückler indicates that Vfw Jakob Landin was the man who got Durrant...
