If I may, the Bf 109 G-4 in question was a "prey" of the 347th FS, and it was "yellow 12", not red...
It was a recce G-4 of 1.(F)/122 found abandoned on Elmas airfield...
It was refurbished and repainted on OD/MG with USAAF markings (but keeping the Luftwaffe unit's badge) and test-flown a few times by Maj. Hugh D. Dow, CO of the 347th FS (shown in the photographs)...
Hope this helps.
