The JG300 losslist shows a Bf109G-14/AS Green 14, lost on January 30, 1945 after the pilot Uffz. Gerhard von Strassmann crashed on take off from Mark Zwuschen while on a ferry flight. Whether it's the aircraft in question is impossible to tell though.
Both colors in the top fuselage camoflage are too dark to be RLM75 so I've opted for latewar colors. The nose seems lighter as does the tail but that wouldn't be unusal with missmatched parts from different productiobatches. The wings are not seen in the picture and could have been in any of the late-war pattern.
