Unusually small barometer with a visible mechanism, curved mercury thermometer, and a flange for fixing it to a wall, or onboard a boat. Fully working, both the barometer and the thermometer, with a chrome plated exterior. The dial measures only 2 5/8" diameter, and the flange, 3 1/2", and has 3 holes. The instrument probably dates to about 1920.
