Vintage air flow meter or Anemometer,
by Short & Mason London. Dial reads No C 1756, 60 - 900 M.P.M.
Incorporates 3 dials measuring 100's 1000's and 10,000's and large sweep
hand on main dial which is graduated from 0 - 100 metres. In full working
order, the vanes turn with the gentlest breeze and all the dials register
as they should. Originally, this device would have been used in mines to
measure airflow, but has now been superceded by more modern digital equipment.
Nevertheless, this is a precision instrument and a testament to the pioneering
technology of the past. Does not come in a case.
