Hi Christophe,
If ObLt Lüder was in any way connected to RIR 133, my guess for the general would be GenLt Max Morgenstern Döring, Kmdr of 24 Res Div the superior formation of RIR 133. I think I can see the general in question wearing glasses like Morgenstern Döring did.
If we stick with LIR 133, then the only Saxon superior formation kmdr that remotely looked like the general in the picture would be Horst v Tettenborn of 45 Ldw Brig. v Tettenborn only became GenMj on 15.07.18 and probably would not be so highly decorated and was fighting on the Eastern Front.
For ObStLt Francke, the conenction to LIR was actually closer. Francke was later Kmdr of IR 179. I/IR 179 was used to form I/LIR 133]
Thanks
Elwyn
Husaren Officer with Flügeladjutant's aiguilette was more than likely at this point Major or Oberstleutnant Harry Freiherr v Fritsch. He was 1 Esk Husaren Rgt 19 and was the only Husaren FlüAdj of FA III I have on my files.
Thanks
