Seeking for help to identify possible DÜPPEL / WINDOW / CHAFF at crashplace of German Bf110 (1 Viewer)

[Kurtl]

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:
https://www.quartermaster.nl/index.php/strip-window-chaff-german- duppel.html
https://historictech.com/product/ww2-german-anti-radar-chaff-duppel-fragments/

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

Regards, K.

Hi Kurtl,
being myself from this part of Austria - may I ask where the location of the crashsite is situated?

Is there any sign of a paper or fabric backing?

Thanks for the interest elbmc1969!
I've checked the pieces of aluminum again, but there are no signs of paper nor any fabric backing. Any clues?

I'll see if I can get you some images and dimensions. There was a reasonable amount of aluminum chaff found in B-26 Flak Bait's bomb bay as it must have had packets that it dropped during the war.
