I'm researching the history of Fliegerhorst Illesheim and am running into conflicting info on the Gruppenkommandeur of ZG-52/Jagdgruppe-152, May-Aug 1939. Unit forming up and equipping with Bf-109D (some sources cite Bf-109B)

Seems a 50/50 split with his name being listed as either Hauptmannn Karl Heinz Lessmann or Hauptmann Wilhelm Lessmann.

I couldn't find any info on Karl-Heinz Lessmann (other than attributing him to ZG-52).

There was a Major Wilhelm Lessman who was KIA with JG-52 in 1942. Not sure if this is the same Wilhelm Lessmann though

Lastly, some cites are confusing Karl-Heinz Lessmann with Karl-Heinz Leesmann -- the latter never serving with ZG-52 or at Illesheim.
