that E127/Kw5 is the radio version made for the state and military.
The differents to the civil version /Kw4 is:

All Plugs are connected to the front plate,
and there was a optional protection mesh (very ugly!)

The radio is a single conversion super using 8 Tubes, the IF is 525 kHz
The IF stage have a crystal filter and allow the selection of 4 bandwiths up to 6kHz.
There are no electrolytics, the radio is complete build with metal paper C and SQ tubes.
The gear train have a pull, 20:1 fine, push 1:1 fast. BFO is there, also a lf filter .
It have a little loudspeaker in the front and a holding for a small document.
The weight is 44kg.
