An exceptional, rare, five glass walnut cased Stormoguide recording barometer or barograph by Short & Mason c1935

Rare Short & Mason Stormoguide Barograph c1935 - SOLD


Walnut-cased barograph constructed mainly in lacquered brass, 3⅝” free floating recording drum struck with “No 7283” and “Made in Baden,” seven day movement, platform escapement and captive winding key. Top cover.

The barometer of standard short chassis Short & Mason design, having eight cell pressure sensing column, floating swinging gate recording arm, calibration adjustment to main cross beam. 4½” silvered and die struck barometer dial, the outer sector to be read for rising pressure and annotated in black with various meteorological prognostications, bounding a zone in red for falling pressure and accompanying prognostications. Stormoguide blued steel pointer. The centre square-form barometric scale calibrated in inches of mercury with a range from 27.5 – 31”, the centre marked with Short & Mason “S&M” logogram, the lower part marked “Stormoguide” and “Compensated for Temperature.” The bottom of the dial annotated “International Copyright, Copyright 1932” and “Made in GT. Britain.” Ink station with ink bottle, frieze drawer. Lift off cover with bevelled lights.

Condition: This barograph has been the subject of a comprehensive re-build and calibration under laboratory conditions, see performance chart below.  All aspects of this instrument are in very good condition, the clockwork mechanism having been completely re-built, as has the barometer which has been set to optimum and now performs with very good sensitivity and accuracy.

The recording arm replaced with a bespoke unit made here at Vavasseur, the nib replaced. Dipper cork replaced. The brass work retaining virtually all original correct frosted lacquer, some discolouration and losses to drum lid. The timber case, which had suffered due to sunlight, has been completely re-lacquered to a high standard. All other aspects of this instrument remain completely original.

Comments: As an example of this very attractive instrument, this has to be about as good as they get. Now very difficult to find in any shape, this instrument seems to have a much better than normal grade of wood used in the plinth and cabinet, with wonderful colour and figure. 

This is a very collectable example, in excellent working condition, and surely one of the few types of barographs that will always be in demand.
