Zenith Porthole Television Set And Tabletop Extension Receiver Appraisal

Zenith 'Porthole' Television Set and Tabletop Extension Receiver

This is a pair of mid-century Zenith 'Porthole' televisions, comprising a console model base and a secondary tabletop unit stacked above it. Manufactured by the Zenith Radio Corporation between late 1948 and 1950, these sets are iconic for their circular cathode-ray tube (CRT) display, which mimics the round shape of a ship's porthole. The console unit features a mahogany-stained wood cabinet with a distinctive speaker grille at the bottom and a set of control knobs flanking the round screen. The top unit is a smaller, tabletop version likely belonging to the G-series or similar era. Both units exhibit significant age-related wear, including scuffing on the wood finishes, missing or loose bezel hardware, and clouding on the safety glass of the screens. The lower unit's control panel door appears slightly misaligned or detached. The circular screens are approximately 10 to 12 inches in diameter. These sets are highly sought after by vintage electronics collectors due to their unique 'zooming' feature, which expanded the 4:3 broadcast image to fill the round screen. The overall craftsmanship reflects the high-quality industrial design of the post-WWII American era, though the current condition shows heavy patina and lack of professional restoration.
