He 111 fixed rear defence
 

While some He 111s had a machine gun in the tail cone, I think that others had a grenade launcher in the same position. I have a generic reference to Störkörperanlagen (literally 'disruptive body installations', although Körper can also mean missiles) but does anyone know what the official designation of this weapon was?

Nick-hasn't this been covered in 2 articles in Iron Cross?

It's also the subject of four un-digitised files at the Bundesarchiv, but I don't have those either! From the file descriptions it seems that Störkörper is all they called it.
