A RARE MAHOGANY CASED COMBINED BAROGRAPH AND THERMOGRAPH OR STORMOGRAPH
RETAILED BY G. PRESCOTT, BELFAST, SECOND QUARTER OF THE 20th CENTURY
The barograph mechanism with eight-segment aneroid chamber connected via a silvered brass armature to an inked pointer for recording the change in barometric pressure on a clockwork-driven rotating paper scale lined drum, the thermograph with coiled bimetallic strip mounted within the same armature operating a second inked pointer, the armature stamped REG. No. 476369 and the silvered collar around the right-hand of two ink bottles engraved G. PRESCOTT, OPTICIAN, BELFAST, the case with bevel-glazed five-panel cover over ogee moulded skirt base applied with silver presentation plate engraved TO MR. J.D. CAMPBELL, FROM THE PUPILS & TEACHERS OF, MOSSLEY P.E. SCHOOL to front, above an apron drawer for spare charts, on disc feet.
23cm (9ins) high, 36cm (14.25ins) wide, 21.5cm (8.75ns) deep.
G. Prescott of Belfast does not appear to be recorded in the usual sources, however A firm with the name George Prescott is recorded in Banfield, Edwin BAROMETER MAKERS AND RETAILERS 1660-1900 as working from various addresses in Dublin from 1879 until after 1901. It is therefore probably likely that the suppliers of the present lot were a branch of this firm operating out of Belfast during the early 20th century. The present lot was probably supplied to G. Prescott by Short and Mason who developed such instruments in collaboration with Taylor Instrument Companies Limited during the inter-war period. Products of this collaboration were mostly sold under the 'Tycos' brand.
Condition Report:
Timepiece movement is in working condition however a gentle clean/service is probably advisable. The aneroid mechanism will respond to change in pressure (has been carefully bag-tested) hence the bellows appear sound. The thermograph also responds to change in temperature hence also is in working order. The mechanism retain silvered finish with minimal wear but with overall patchy oxidation and some micro-bubbling to the baseplate plating. The ink bottle is stained but appears undamaged. The case is in good original condition with faults very much limited to minor bumps, scuffs and other age-rleated blemishes.
Instrument is complete with winder for the clockwork mechanism and a quantity of spare charts.
