Art Deco French Barometer by Barostar Instrument Makers

Art Deco French Barometer by Barostar, Instrument Makers, Paris. Ideal for Weather forecasting and has the secondary needle to position at current Atmospheric Air Pressure. If the active needle moves clockwise, pressure increasing, good weather approaching, and vice versa. The Dial is in Hpa and mm. The previous owner was meticulous and there is evidence he had the rear of the barometer cover with light paper to keep dust out. The rear case has an adjustment screw for fine corrections after shipping or major Altitude relocation. Excellent condition with a soft aged patina. France.
