Rare Brass Antique Colliery Air Flow Meter, L. Casella - London, Velometer / Anemometer, with original wooden box.
Very rare to find these air meters, with 5 different measurements - 10,000s, 1,000s, 100s, 10s and feet. I cannot find another one for sale anywhere! Good working condition for age, with some superficial tarnishing, scratches and wear.
Box - some wear and discolouration plus, faint writing to the inner lid. Testing airflow in colliery workings was essential to ensure proper ventilation. Casella was a well-known maker of scientific instruments of all kinds in London during the second half of the 19th century.
