Hard to find larger size antique. Brass aneroid compensated barometer used for surveying. Most likely from the 1910s-1920s? This is not the pocket sized model. Measures 5″ x 5″ wide (not including lens and knob), 3 deep. Weighs approximately 2.5 lbs. Not sure if currently functioning, but when a magnet is placed near it, the needle moves. So perhaps it might function if serviced? The glass is intact with no breakage. Does not include case. Ships to US only.
