Thanks to Tim Wheeldon for the heads-up on this footage.
The Gustav looks to be a 'hybrid' of standard G-6/G-14 with red legs and 'later' parts - an 'unrefined' cowl, small 'early' tail, small wheels/tyres but with red gear legs and the wider wing bulges.Note too the Erla-haube. ..
" ..'yellow 11' is actually Mtt built Bf 109 G-6/R2 W.Nr. 230785 "Gelbe 11", operated by 3./NAGr. 13. According to our friend Charles Bavarois, W.Nr. 230785 is reported by ULTRA Hw5/686 as being at Fritzlar Werft on 30 March 1945 with 3./NAGr. 13. This is the very day Fl.Pl. Fritzlar was overrun by the US Army with some striking photos made by US Signal Corps during the action.."
According to another source 'Gelbe 11' was produced in a a very late production run of 200 G-6/R2 machines. All aircraft in this batch were built as tactical reconnaissance fighters during November and December 1944, just three months before German Bf 109 production came to an end. These aircraft were the last G-6 machines built by WNF, and by the time of their construction the supply chain consisted of late model parts. Note the supercharger intake on this aircraft is the type introduced for the later asymmetric cowls, lacking the cutout on the upper flange for the fuselage beule. Additionally the machine has the late style colored lens (red/green) on the wing tip navigation lights and the the large wing bulges.
I was sent an message recently that asserted that this machine was on the strength of JG 4 - I see no evidence for that at all anywhere. Nearly all JG 4 109s wore the 'Defence of the Reich' fuselage bands
