A top quality wall barometer by the London maker John Wardale. The octagonal mahogany case is in lovely condition. It measures approximately 10 across the diagonal. The silvered dial measures approximately 6 across. The movement has been calibrated but fine calibration might be required for the most accurate readings. The exact age is uncertain, but an educated guess would be 1910 – 1920 based on the back being stamped English Made rather than Made in England. English barometers of this period were the best available.
