antique Dutch brass aneroid barometer

Very nice and complete antique brass barometer, rare, especially the worked part gives extra insight into the technique. This type of barometers is called Bourdon barometers. The barometer is signed underneath with L.J. Harri Amsterdam, not sure if this is the seller or the maker, because on the back of the barometer PHNB is stamped in a circle. Below the barometer is another thermometer. At the top of the barometer, the air pressure is read in cm mercury column and also in Dutch the status from storm to very dry and everything in between.
