Negretti and Zambra LTD Anemometer +

I have a Negretti and Zambra ltd. Anemometer. Used mainly for the measurement of airflow through Scientific and Engineering equipment, and also in the Mining industry. It is a very nice example constructed in a black lacquered brass frame which is about 5” in diameter. The dial face is framed with non-lacquered brass detail as is the handle and on it’s face there are 3 individual dials each with individual hands. Across the dial it reads ‘Velocity In Feet’ and has the serial number: No I 958. The Anemometer has it’s original quality brown leather case and burgundy lining. I am open to offers. Free delievery within 10 miles but can also post with recorded signed for delievery.
