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.

I have virtually examined this rare pairing of Zenith 'Porthole' television sets, consisting of a floor console base and a supplemental tabletop receiver. These units, likely dating to 1949-1950, are iconic representations of the transition from early post-war television design to the 'golden age' of broadcasting. The presence of the circular CRT is a hallmark of Zenith’s engineering, specifically their attempt to maximize screen area before rectangular tubes became industry standard. My assessment of the condition reveals significant surface degradation, including 'cataracts' on the safety glass (caused by the decomposition of the PVA adhesive layer between the glass and the CRT), which is typical but requires costly restoration. The mahogany veneers show moderate scuffing and moisture damage consistent with long-term storage. Authentication of the 'Porthole' series is largely confirmed by the unique bezel design and knob configuration; however, without a physical inspection, I cannot verify the integrity of the internal chassis, the presence of original vacuum tubes, or whether the CRTs are 'gassy' or internally cracked. Market demand for these sets remains high among mid-century modern enthusiasts and technical collectors due to their architectural silhouette. While a fully restored, functional pair could fetch upwards of $3,500, the current 'as-is' condition limits the value primarily to the 'project' market. A definitive appraisal would require removing the back panels to inspect for component leakage and verifying the model numbers (e.g., G2322R or similar) on the serial plates. The valuation assumes the CRT faceplates are not physically scratched beyond the adhesive clouding.
