Hi Theodor,

Doesn't look like a radio part to me. Then again I'm not much of an expert an radios.

Telefunken manufactered a bunch of other stuff too, such as radar systems (Würzburg) and radio tracking devices (used by the German Abwehr to track spy radio transmissions). I think these last ones are called "Nähfeld-peiler" in German.

Hope this helps,
Rudi.
