Significant Shipwrecked Mariners Society Award – Updated March 2025
Generally when these instruments are given as presentations it’s to a retired partner from a law firm or the winner of some golfing extravaganza - these additions add nothing to the value or interest in the piece, indeed in most instances the plates are removed, the holes filled and a part of ignominious history gently forgotten. The Shipwrecked Fishermen and...

Shipwrecked Mariners’ Society Marine Barometers in Unusual Cases
The Shipwrecked Fishermen and Mariners’ Royal Benevolent Society, better known as the Shipwrecked Mariners’ Society, was established by John Rye in February 1839 as a result of the tragic loss of a fleet of fishing boats on the north Devon coast in October 1838. The Society’s objectives were to give “relief and assistance to the widows and orphans of fishermen;...

On This Day – 8th August 1908 – Wilbur Wright
On this day in 1908, Wilbur Wright publicly demonstrated a Wright aircraft for the first time in Europe at the Hunaudières racecourse at Le Mans, southwest of Paris. The airplane was an improved version of the brothers’ experimental designs flown in 1903-1905. Wilbur’s flights at Le Mans confirmed without doubt the Wrights’ claims to have developed a successful airplane and...

Hysteresis and the Watkin Hicks Mountain Barometer
This scarce development of the aneroid barometer or altimeter, patented by Colonel H.S.S. Watkin in 1898, was born of poorly performing pressure sensing capsules. It had been known for some time that a first reading before an ascent of some high place would not agree once the observer returned to the same elevation even if the barometric pressure had not...

August Work in Progress
Another fine instrument of particular interest, this large barograph is something quite special, and although unsigned, is undoubtedly the work of Negretti & Zambra. Let’s examine the evidence for this. First, the instrument is listed in the Negretti & Zambra catalogue of 1910 in the section Self-Recording Aneroid Barometers: item 82, a “Self-Recording Barometer, with a tall cylinder taking a...

The Quest for Greater Resolution in Aneroid Barometers II
As a follow up to Patent No. 2457 lodged by Daniels, this piece is certainly of significance. The Daniels instruments sought to display greater resolution with the introduction of a geared sub-assembly greatly magnifying the small rotational movement of the primary arbor, that connected by a fine chain to the secondary lever - the result being that the main dial...

The Quest for Greater Resolution in Aneroid Barometers I
As marvellous an invention as the aneroid barometer was, it had many shortcomings, most of which were approached by various instrument makers over the 100 years or so of production. Resolution, perhaps expressed as the reading to the highest number of decimal places, was an illusive goal. The problem relates to the expansion and contraction of the cell over a...

Antique Pocket Hypsometers I – French Hypsometer
The term 'Hypsometer' is essentially applied to a device or system, perhaps mathematically based, that enables the determination of heights or elevations. It has been applied to aneroids and various trigonometrically based instruments. In this instance we are dealing with the instrument more generally recognised as a hypsometer, in essence a device not unlike a telescope however lacking lenses, the...

March Work in Progress
Another fascinating instrument from the storeroom, and at last I can give it the attention it needs. This Negretti & Zambra barothermograph was absolutely filthy, caked in dust and grime, and working to a point but not much more. Nonetheless, I could see that this would come good with careful conservation techniques. I always start a project like this by...

Many might wonder what might be next on Vavasseur Antiques. “Work in progress” is a constant state, since almost all the items we offer are comprehensively re-built, serviced, and/or benefit from conservation. Consequently through-put is sometimes slow. This does mean though that the things we offer are ‘proper,’ as described, and as original as possible, not the product of the...

Testing Aneroid Barometers for Accuracy & Function
Aneroid barometers that have not been properly serviced and calibrated may be prone to one or more of the many common faults that are found and the oft-cited Plastic Bag Text is fallible. Buying an instrument that has not been properly checked is therefore a lottery.

Unfortunately, as the programme was set in 1830s, as pocket barometers weren’t invented until Negretti & Zambra rose to…
