DescriptionVintage TMK 10-Transistor AM Radio (No Model Number), Reverse Paint Sliderule Dial, Made in Japan (8507489229).jpg
This radio was marketed under a number of brand names. I have a few of them in my collection and will post photos of them. I'm not sure of the manufacturer. I was told it was Koyo Denko by one collector. Another possibility is TMK Toyomenka (America) Inc., Secaucus, NJ. I would appreciate any information you may have on the manufacturer.
Note: it resembles Koyo KTR-624 (1961), a best seller model at that time, seen on top of "Nostalgia of audio equipment" page in Koyo Electronics Industries' Fifty Years History (2009).
