Tube to radio ?

[Mickesouth]

Hi all. I wanted to ask what this item is. I think it belongs inside an radio ?? Its stamped with small eagles and what looks like Wa 801. The tube it self is made by Tungsram but the paper packet from Blaupunkt.

You're 100% correct. Nice example and packing. Any idea what type it is ?
