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measure airflow, but has now been superceded by more modern digital equipment.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.

Unusual item, anenometer by Negretti & Zambra.
Dial reads 'AIR METER TO 100,000 FEET'. Dates to around 1920-1930 and comes
with its own leather case with separate screw in adaptor which appears to
be for fixing to a tripod? In good condition, although the dial has some
minor discoloration which would probably clean off. All appears to be in
working order, the dials turn when the vanes spin, and dials can all be
reset to zero. An interesting item which no doubt will whet the appetite
of N & Z collectors.
