A barometer is a scientific instrument used in meteorology to measure atmospheric pressure. Pressure tendency can forecast short term changes in the weather. Numerous measurements of air pressure are used within surface weather analysis to help find surface troughs, high pressure systems and frontal boundaries.
Made of brass and aluminum, by the Yanagi Manufacturing Co., this piece is of late-war manufacture. Complete with the original paperwork, adjustment tools and key (these are usually missing), it has some very slight marks, scratches, and wear due to the age, but is EASILY the most complete and nicest examples I have seen! All data information is printed on the dial, and data plate, indicating type & manufacture date (March 1945), and production number. NO corrosion, and is 100% FUNCTIONAL (thougn I am not sure how acurate)! Brought back by a US Veteran, it will comes complete in the original wood transport box. Like most Japanese WW2 items, this indicator is VERY RARE, and would make a PERFECT addition to any Japanese Instrument or Radio collection!
