Nickel Plated Brass Motor Aneroid Barometer Altimeter by Chadburns c1920 – SOLD
Motor aneroid barometer with 2½” struck and silvered dial having dual concentric scales, the outer rotating altitude ring marked “Ascent” and “Descent,” depicted in black and red respectively and divided into +/- 2,000ft. The inner barometric scale calibrated from 27 to 21 inches of mercury. The upper dial marked “Motor Aneroid,” the lower portion signed by the maker, “Chadburns Ltd, 47 Castle Street, Liverpool.” Blued steel pointer set beneath a bevelled glass within a rotating outer bezel. High quality 1¾” capsule driven frosted lacquered brass movement of conventional pattern set on a heavy circular chassis. The whole contained within a nickel plated drum form case with mounting flange. Compensation adjustment to verso.
The glass having some fine scratches and localised chips to bevelled edge, the dial with minimal signs of ageing, the nickel finish with signs of dulling, minor abrasions and wear. Overall crisp good condition.
Now really quite hard to find especially in good condition, sought by collectors of barometers and automobilia alike, these instruments were fitted to the more prestigious motor cars of the times, particularly Rolls Royce and, later, Bentley, the nickel finish being particularly synonymous with the general finishing of the metal parts within these vehicles and the general appearance of dashboards. Many of these instruments were also fitted after market as an essential embellishment or accessory to any fine motor car.
Though the dial is marked “Chadburns,” we have noted a number of very similar instruments, almost identical in presentation with a range of dial signatures. This is almost certainly because of the demand seen through the eyes of many different quality retailers who acquired these motor aneroids from one or possibly two manufactures, and subsequently adding their identities. The movement appearing to be of first quality construction, the most likely maker is Short & Mason.
