Notice the red/yellow band for JG301.
At that time IV./JG301 was flying G-14s.
I would imagine that's simply a made up paint scheme, as it has a JG 301 Reichsverteidigung band, Eastern/Balkan front wingtip markings, JG 27 unit insignia on the cowling, and air to ground kill markings on the rudder despite the lack of an ETC rack or markings of a Jabostaffel.
It is an F- the tell-tale signs being the glazed section of fuselage below the windscreen, fuel filler point below the cockpit (moved to the spine of the tail behind the cockpit in the G series), strengthening struts where the tail attaches to the tail plane, and shallow oil cooler.
It's definitely NOT a G-14, due to the things previously mentioned, the lack of bulges for MG 131's, neither an Erla Haube canopy or an extended vertical stabilizer/rudder (not tell-tale but unlikely for a G-14), the radio mast and the retractable tail wheel (last aircraft built with this were late production G-2's until it was reintroduced in the K series)
