WW2 German Luftwaffe Glimmröhrensummer – MORSE KEY TESTING UNIT – VERY NICE!

Made by Seibt, AG, of bakelite, aluminum, and steel, this item is of late-war manufacture, and was brought back by a US Serviceman. As it is in used condition, it does feature various marks, scratches, and wear, but nothing that detracts. 100% COMPLETE, and mechanical functional, however, I have not tested it for electrical functionality, so I am selling this set as-is. Has three connectors: two for headphones (Fernhoerer); and one for a the Morsetaste (Morse Key). Marked 110-220V with an off-on switch (Aus-Ein); two knobs one for Volume (Lautstaerke); and one for Tone (Tonhoehe). Retains the original data plate, clearly indicating the type and manufacture…as well as various Luftwaffe BAL Inspection stamps. Original cord and plug are also present (some fraying on the cord). Would make a VERY NICE addition to any collection or display!
