 The Zenith 'T/O' began life in 1942 as the Model 7G605 'Trans-ocean Clipper'.Priced at $75, it was released in January but ceased production in April as Zenith shifted their production to war-related equipment.During this short production run, some 35,000 units were produced and sales data showed that many were sold to customers in the 'above average' income group.
