Wehrmacht '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 1942. The device is complete with a replacement wire and plug. The set is in good used condition, there is some minor bakelite damage, see close up. Very nice and quite scarce piece of equipment!
