Hi Chis,
FWIW, I did find a secondary-source confirmation for Armin Goebel as StaKa of 1.(F)/123 at Toussus-le-Noble/Buc in Feb 1942.
According to Harald Rabader's "The Knullenkopfstaffel", Oblt. Goebel was Staffelkapitän of 1.(F)/123 from 26 Nov 1940 to 16 May 1943. He was promoted to Hauptmann on 1 Feb 1942.
(However, I suspect that you're already well aware of this resource...
)
No luck on 3.(F)/122 or 3.(F)/123, unfortunately.
Regards,
Leon Venter
