Tempest / Mellow tone TR604, 1964
I finally found a blue one just like the one I had as a boy. I recently rediscovered the diaries I kept for a few years in my youth. An entry reveals that my father bought my blue Mellow tone radio at the A&P grocery store on Boston Avenue in Bridgeport, Connecticut on January 20, 1964. I dimly recall that I, age 10, was with him at the time.
