Tesla's first shirt pocket transistor radio. As a resident of Bratislava, I can tell you that ANYONE I talk to here (not just collectors) remembers this little radio with a true touch of nostalgia — unfortunately, they also remember it as being a pretty crappy radio in terms of performance.
If you look at the chassis image below, you'll notice that the tuning dial isn't calibrated in kHz or meters, but simply 0-10. Another set I've seen this on is the 1962 Mir, a Soviet radio manufactured in Belarus. I really can't say why this dial numbering scheme was chosen for either radio.
