Luftwaffe bakelite morse training device or Morseübungsgerät

Rare bakelite Luftwaffe morse training device. The Morseübungsgerät is in good condition and nicely marked A. Grote & Söhne G.m.b.H. Köln Zollstock – Morseübungsgerät MÜG 3. The device was used with two headphones and morse keys. The instructor would send a message in Morse and the student would receive and note the message. A nice short introduction to the Morseübungsgerät can be found here.
