Mark I Compensated Barometer
by T.Wheeler Scientific Instruments Ltd. London
No.7295 / 41
Very nice example of an early to mid 20th Century barometer. It is cased in a metal mount, painted army green with glass covering the face. There is a ridged brass ring around the face which can be turned to set the pointer. The face is marked with the makers name and the serial number. It is also marked MO which indicates it was made specifically for use by the Meteorological Office, either in their weather station or a weather boat. The casing has screw holes for mounting which leads me to believe it is likely from a boat.
It is in good condition for its age. The glass is clean and has no major surface scratches. The face is generally clean with just a few small age related marks. There is some paint loss on the casing and a few general knocks and scuffs and some light scratches but only what is to be expected. It displays very nicely. It seems to be in working order - the pointer is certainly moving but i cannot guarantee its accuracy and it is really being sold as a decorative collectable item rather than an accurate scientific instrument.
