ref.1955

A 5 ½” diameter brass cased Bourdon barometer, instrument number 25224 with reverse printed glass dial of traditional design, the trade mark S L either side of a three branched candelabra marked on the dial. The outer case cleaned and re-lacquered with a traditional lacquer used on early instruments (this mixture we prepare specially from an old recipe which includes natural tree gums, saffron and dragons blood!) the whole in good working order, dating c1900. This curious alternative to the Vidi aneroid movement is a good example, complete with key (replacement) for altitude setting. See Aneroid Barometers and their Restoration, chapter 10 page 184 concerning Bourdon barometers. £750
