..looks like the markings are simply based on that 90s German rebuild. I./NJG 11 did fly the latest Bf 109 G-14/AS and G-10 models for Moskito-Jagd as reported by Feldwebel Walter Schermutzki so I guess the artwork is a 'best guess'. Gniffke said he flew the unit's last sortie - ie April 1945 - in Müller's K-4 which featured the usual chevrons of the Gruppenkommandeur. See my Eduard INFO feature on Müller.
