Well, here's a beautiful precision aneroid barometer, ex Royal Ordnance Factory dated 1989 manufacture and complete with it's original factory calibration sheet. This amazing instrument has a scale length of 16 inches which in conjunction with an anti-parralax mirror allows precision anlogue readings of atmospheric absolute pressure to be made in the range of 660 - 800 mm Hg.
This device, already heavily built is supplied on a heavy metal backplate for mounting stability.
