Philco 50T1443 12 inch Consolette. Control knobs are concealed behind a hinged drop down door below the picture tube. In 1950 12' all glass picture tubes started being manufactured. Prior to that time any tube larger than 10 inches was made with a metal funnel fused to a glass face and glass neck. With the introduction of the 12LP4 all glass picture tube, many more 12" sets became available. This 12 inch Philco was just one of the many 12 inch models that Philco produced in 1950.
