Snow Storm 9-10 Dec 2017

The instrument, its cabinet disassembled, cleaned and polished, the mechanism cleaned and serviced, remains entirely original in all respects. The recording paper for an up-to-date test shows good sensitivity and function. The test trace shows the steep drop in pressure caused by the snow storm here in Shropshire over the weekend.

Instruments with this combination of barograph and aneroid barometer may be considered scarce. The majority found as untouched require re-lacquering to the case due to sun damage. This Short & Mason barograph is particularly unusual in that the mechanism and its oak case are in such good original condition. It has restored very well.
