THE MAIN SHIP'S BELL FROM THE R.M.S. LAURENTIC, 1908
cast in bell metal with name inscribed over an arc with black-filled lettering, single hanging bracket to head (lacks clapper staple and clapper, pitted lower right on exterior) - 19 x 17 x 14in. (48 x 43 x 35.5cm.)
Provenance: Bembridge Maritime Museum
£10000-15000
Built, as all White Star liners were, by Harland & Wolff, Belfast, the Laurentic was registered at nearly 15,000 tons and could carry about 1,700 passengers over three classes, plus crew. She enjoyed her first brush with fame in July 1910 when Chief Inspector Dew of Scotland Yard boarded her in order to overtake the S.S. Montrose and apprehend Dr. Crippen and his mistress. In the Great War she maintained passenger services but was also registered as an auxiliary cruiser. On January 23rd 1917 Commanded by Capt R.A. Norton, she left port in fine but bitterly cold weather. About an hour later she struck two mines laid by U-80 in Lough Swilly and sank in just 45 minutes. Fifty-two officers and 316 ratings were saved but 475 died in the freezing seas. It later transpired she was carrying a cargo of 3211 (45 tons) in gold bars then valued in excess of £5 million - over 390 million today. All but 25 of these were subsequently raised by the Royal Navy in the 1920's and a further three by a private company in 1934 - the remaining 22 bars are still unaccounted for. The wreck was bought for £100 in 1969 by hobby diver Ray Cossum who, in 1979 raised this bell and sold it to the Bembridge Maritime Museum in 1993. The pitting seen lower right is believed to have been made by a crewman who used a hammer to sound the alarm whilst the ship was sinking

This instrument was selected to time these flights as it was supplied to Peter L. de Mory Gray, one of the earliest suppliers of navigational instruments in America. The accompanying notes state that it was carried on this first supersonic flight between England and America 'in recognition of the ties which, like the original 'Longitude Project' of the last century, continue to unite our two countries in this year that marks the Bi-Centenary of the American War of Independence'. The information contains lists on BA paper of all the Concorde cabin crews, the passenger list including political and media representatives; associated data concerning the transport of this instrument and a certificate for the flight from London to New York in 1977 when that route opened to Concorde.
The instrument was chosen by Lt. Cmdr. David Harries, RN, a renowned chronometer specialist, for its UK-US connections, and entrusted to and carried by Gordon Davidson, Director of Concorde, in all of its inaugural supersonic flights.

A RARE, POSSIBLY UNIQUE, W. MARSHAM ADAM'S COELOMETER, CIRCA 1874

Wyld mounted on rotating axis with elliptical true horizon indicator ring, equinox ring and detachable hinged star cage set with gilt star constellations stamped with names as appropriate, the whole mounted on a single swiveling bracket with threaded securing nuts on turned wooden base with inset maker's label inscribed ADAMS'S CŒLOMETER, set in later ebonised wooden display base with glass dome (dome cracked and missing section). The Coelometer - 20 x 18in. (51 x 45.5cm.)
Literature: Nautical Magazine, November 1874, p.1025-1026.
This instrument was designed to instruct and test naval cadets in their navigational proficiency. According to the above-mentioned article W[alter] Marsham Adams (1838-1899) was a former Fellow of New College, Oxford and seems to have been an author on various subjects, and an inventor having sent no less than three to the Vienna World's Fair Exhibition of 1873 of which this was awarded a medal: the Coelometer exhibits in a concrete form all the conceptions which are necessary for nautical astronomy and the relations which exist between them.. In prosecution of this object, it occurred to him to devise an instrument which should illustrate physically the conceptions of celestial latitude and longitude, as well as right ascension and declination. The method of representing the true horizon soon afterwards suggested itself, and subsequently the corrections for dip, parallax and refraction were added. By these means the whole theory of nautical astronomy becomes evident at a glance. The article later mentions that both the Training Ship Conway and the President of the Naval College at Greenwich planned to place orders for examples and that soon every training college, examining department and every ship and school would acquire one - to date this lot is the only example sighted in any public or private collection and it seems likely that the expense of such an instrument compared to traditional techniques thwarted the author's confident prediction
