Gentlemen,

the picture attached shows pieces of crumpled aluminum I've just found at a crashplace of a German Bf110 in the eastern part of Austria. First I thought that these might be remains of food wrapping lost by somebody during forest operations. When I found one of these pieces grown into a large spruce tree I got curious. Could it be fragments of Düppel used to interfere enemy's radar?

Though I haven't identified the crashed aircraft, but according to locals it was a Bf110G-2/R3 of II./ZG1 shot down by a P-38 on May 29th, 1944. So definitly involved in daylight operations...

Decrumpling some of these pieces show that they all have the same dimensions: ~35mm wide and up to 295mm long so far (but broken on both ends). The thickness I can only guess - very thin, far less then 1mm.

I already found this on the internet:

I guess they used different dimensions but I have found no details so far. Any help is greatly appreciated.

Regards, K.
