Notes Toshiba came back to production of radio set after the war. A few Toshiba radio in early 1940's was OEM supplied products. After the war, they produced radio set at own factory. Model ZS-1004A was one of the Toshiba's first products and hi-end set. Design was early 1940's American style. Finish was poor but construction was solid and strong. The design of prototype was different from production model. 3 variations of cabinet existed on the production model. Chassis was not changed. Quality was falling down in proportion to minor change by inflation and lack of material.
