This antique Aneroid banjo barometer, carved from oak in the early 20th century, is a rare and valuable collectable piece. As a scientific instrument from the period between 1901 to 1950, it holds historical significance and is a unique addition to any collection of vintage scientific instruments or barometers. The intricately carved wooden design adds to its charm, making it a standout piece for any enthusiast of antique scientific objects.

I don’t know if this works but the bottom hand on the barometer does change but the thermometer part doesn’t seem to show any signs of working.
