Luftwaffe 'Mouse' Morse Key (Morsetaste TKP "Maus"). The Morse key 'Mouse' was mostly used with radios in armoured cars and tanks. The device is nicely maker marked with 'dbf' indicating production by the company of 'Hoppmann & Mulsow' from Hamburg and dated 1941. The device is complete with original wire and plug. The set is in good used condition and mounted on a plexiglass plate, removable. Very nice and quite scarce piece of equipment!
