An oak-cased Cyclo-Stormograph by Short and Mason, a barograph in which the vacuum chamber and the first link are housed underneath the base plates.
In 1921, Short and Mason obtained a copyright for their theory that a storm forecast could be made from just observing the air pressure and whether it was rising or falling. This barograph has a plaque engraved with that weather forecast, the predictions then correspond to the letters A-K marked on the charts.
The 8 day clock drum is stamped SWISS 11 JEWELS ADJUSTED, with protected cylinder escapement and fixed key.
The barograph bears a plaque and is stamped for the original retailer Thomas Armstrong & Bro. Ltd., 78 Deansgate, Manchester and numbered 3210.
The oak cover is glazed on 5 sides.
