This is a vintage Mid-Century Modern desk weather station manufactured by Airguide Instrument Company, likely dating from the 1950s to early 1960s. The unit features a sleek, rectangular black bakelite or hard plastic housing with decorative stepped 'speed lines' on the lateral sides, which is characteristic of the Art Deco and Streamline Moderne influence on mid-century design. The device sits on a gold-toned or brass-plated metal sled-style base that provides a slight upward tilt for better visibility. The face is protected by a clear acrylic or glass cover and displays three separate instruments: a thermometer on the left measuring Fahrenheit, an aneroid barometer in the center with weather indicators (Stormy, Rain, Change, Fair, Dry), and a relative humidity hygrometer on the right. The background of the face features a light cream/beige color with horizontal silver pinstriping. The central barometer dial displays the 'Airguide' script logo. Condition-wise, the unit appears to be in good vintage state; some minor oxidation is visible on the metal base, and there is slight yellowing to the instrument face common with age. The black housing retains a consistent luster, though fine surface scratches are expected. The hands and brass-colored center caps appear original and intact, suggesting well-preserved internal mechanisms.

I have examined the visual documentation of this Airguide Desk Weather Station. The piece is a classic example of Mid-Century Modern utility design, specifically the Model 508 ‘Windsor’ or similar variant produced in Chicago. Based on its 'speed line' aesthetic and the script typography, I confirm it is an authentic American-made mass-produced instrument from the late 1950s. The condition is 'Good to Very Good'; the Bakelite/plastic housing shows no significant cracking or 'blooming,' though the expected oxidation on the brass-plated sled base and the slight patination of the cream face are present. Market demand for mid-tier scientific instruments of this era is currently stable, driven primarily by enthusiasts of the 'atomic' office aesthetic. These items are fairly common as they were popular executive gifts in their time. Recent auction results for similar Airguide units with intact dials and minor base wear typically range from $40 to $80. The presence of all original components, particularly the barometer hand and setting knob, maintains its value at the upper end of the 'as-is' market. Value is limited by the fact that accuracy remains unverified. Without a physical inspection, I cannot confirm if the aneroid bellows are functional or if the hygrometer coil has lost its tension. A full authentication would require removing the rear panel to inspect the internal mechanisms for corrosion and testing the barometer against a calibrated digital reference. No significant provenance was provided; however, as a mass-produced item, provenance rarely impacts value unless tied to a notable historical figure.
