This is a working mining aneroid barometer by specialist makers, John Davis of Derby. The distinctive buff coloured dial shows a much broader scale than standard surface barometers (27″ to 33″) enabling the barometer to function well underground. This substantial barometer, set in a copper & brass case, has a curved thermometer in a Fahrenheit scale in the lower half.
