Antique Holosteric Barometer - Weather Forecasting Instrument with Thermometer #23264 (License: Personal Use)

This intricately engraved antique barometer features dual scales-pressure in inches (28-31) and temperature in Fahrenheit (0-100)-with labeled weather conditions including “Stormy,” “Much Rain,” “Rain,” “Change,” and “Fair.” Its central dial reveals the internal aneroid cell mechanism, while side-mounted thermometers and calibration markings (“Set Fair”) highlight its dual functionality. The device exemplifies Victorian-era scientific instrumentation designed for home or maritime use.
