I have a very similar/identical NorMende Electra, I paid $10.00 for it at a Thrift Store. Speaker wires were disconnected and acouple of the Knobs were missing, the case was/is in great shape, including a good tuning eye. The radio worked well. However I don’t think I would get much for it, These German Radios, are usually enginered well and are good performers. On some sites the asking prices can be more than I believe them to be worrth. If this were an AEG Super Banjo or something similar, it would possibly bring a lot more. Clean it up and figure out what you got into it and test the waters. How badly a buyer wants it, will determine the going price.That’s about all, I myself can say, advise wise.
