Please find the original description below taken from the accompanying literature.
This fine aneroid instrument faithfully reproduces many features, including the Prince of Wales Feathers finial, a feature used on many the handsome Royal barometers which the eminent maker John Russell of Falkirk supplied to King George Ill and the Prince Regent.
The mahogany case, which also houses a mercury thermometer, is enriched with polished and twisted brass, and decorated with black and gold glass panels.
The white-painted dial includes two subsidiary dials. Russell was a technician of ingenuity and industry. He invented a reduction system by which these inner dials give equivalent readings to those on the outer scale to no less than 0.001. The main dial has a normal scale of 28 inches being divided into tenths.
The inscription on the dial reads, WatchMaker to his R.H.The PRINCE REGENT similar to that on the Victoria and Albert Museum instrument.
The mercury thermometer has two scales:
fahrenheit and Royal Society. The latter recalls an attempt by the Society to obtain international agreement on the adoption of one universal temperature scale in place of several alternatives then in use. Another feature of surviving Russell instruments is reproduced on the thermometer scale, significant temperature levels being named in a "hand-written" style They are: Fever Heat, Blood Heat, Very Warm and Agreeable Temperate and Freezing.
There is a plaque to the rear of the barometer.
MADE TO COMMEMORATE THE MARRIAGE OF THE PRINCE OF WALES AND LADY DIANA SPENCER. 29th July 1981.
