R-870 M

is a fully transistorized Russian Air Band receiver, with a frequency range of
100 ... 150 MHz.

This specimen was adapted by the German Army; they added a new front, and changed part of the structure.

The original radio had 12V DC and 220V AC in one connector; this is not allowed in Germany. That is why the AC PSU was removed, leaving the 12V input only. So the empty room inside the housing resulted.

I could not find any hints about the conversion or about the "Germanizing..." of the front plate.
