Today I found this site on the net,
http://www.13tharmoreddivision.org/page1.html
there are two nice photos, the first of a ju88 with wnr. and the other one of a dump with some wrecked jumo 004 and a tail with a swastika that seems to have been impressed on a piece of paper and then glued to the vertical surface. Please notice how the lower part of the symbol seems to be slightly detached.
Any ideas?
