This photo(from my collection) shows at least two later-to-become Knights Cross pilots. In the middle we have Hermann Graf and far left is Anton "Toni" Lindner. The photo is probably taken in Merseburg where Graf was an instructor in the beginning of 1940.
"...On 20 January 1940, his Gruppenkommandeur (Group Commander) Hans-Heinrich Brustellin had Graf transferred to the Ergänzungs-Jagdgruppe Merseburg (a supplementary training unit stationed at Merseburg) where he provided newly trained fighter pilots from the fighter pilot schools with combat experience as an instructor."

Can someone confirm this - and perhaps also put some names to the other faces on this photo...?
