WNr.112372, yellow 7 of I./JG7
This aircraft was originally test-flown on 23 March 1945 and subsequently delivered to JG7. The British then captured it at Schleswig. Became AM51, now on static display Aerospace Museum at Cosford. Haven't seen the "x" on this air-plane before.
Very odd paint job. This is how it was displayed by the RAF museum in 1976.
It didn't look like that when captured at Schleswig. It was marked 'Red 2' with the number neatly applied on the nose over the JG 7 emblem which is still faintly visible. It also had the JG 7 RDV band and no X in front of the balkenkreuz. Instead there is an over painted number, probably a 2,4 or 7.
It is now more sympathetically restored as 'Yellow 4'. One colour, no mottle for those modellers who hate Luftwaffe mottling
