A ‘Royal’ barometer by John Russell, Watchmaker to the Prince Regent

This superbly crafted wheel barometer and thermometer has a mahogany case surrounded by twisted brass stringing and central panels of foliate tendrils above Russell’s signature thistle motif in black and gilt verre églomisé. It is surmounted by a brass Prince of Wales feather finial. The long, rectangular thermometer plate is inscribed ‘Thermometers: Beaumar, Fahrenheit, Royal Society of London’, the latter being an early attempt to standardise temperature measurement. The circular dial is inscribed ‘Changeable, Fair, Settled Fair, Much Rain’ and ‘Rain’ and signed across the centre ‘J Russell, Falkirk, Invt et Fecit, Watch Maker to his R.H the Prince Regent’. The reverse has a paper label ‘Russell, Iden Collection Inventory 1896’. Scottish, circa 1815.

Estimate:£58,500
