Vintage AIRGUIDE INSTRUMENT COMPANY Airguide Barometer. This instrument measures Temperature, Barometric pressure, and Humidity. The piece has a small chip on glass on corner. See pictures for sample. The temperature for fine. Gave two sample pictures to show it works. I am not sure if the barometric pressure or humidity works. I am not sure how they work. They seem to be okay, and working. Not sure, though. The needle on the Barometer moves when you move the unit. This is why the needle is different of two of the pictures. Not sure if this is normal?
