Hi D.B.,
Thanks for your input. There are two pictures known for this plane which, according to Eric Mombeek is a 1./JG 4 plane.

After checking out the possible location for this wreck on Michael Holm's great site, it might have been left behind in Darmstadt, where I./JG 4 was based until 22 January 1945, and found by a US unit in March when the city was overrun.
Cheers
Marc
