The Trav-Ler TR-610 is a beautiful little transistor radio, which was manufactured for the Trav-Ler Radio & Television Company of Indiana (USA) by the Japanese company Matsushita.
It is quite a scarce set under the Trav-Ler brand, although it was also manufactured in more plentiful quantities by Mansushita and sold under the National Panasonic brand as the model T-19. Theres is also an equivalent set under the Truetone brand model DC-3160.
