Just came across this. Could be an interesting opportunity for an institutional acquisition.
adapted from Bonhams press release: An important two-day marine chronometer from HMS Beagle, the legendary Admiralty survey ship that took Charles Darwin on an epic five-year voyage to South America and the Galapagos Islands, has surfaced at Bonhams. It will be offered in the 9th July Fine Clocks sale at New Bond Street, London with an estimate of £30,000-50,000. The previously unrecorded marine chronometer, dated 1825 and signed by William Edward Frodsham, was one of 22 that were on board HMS Beagle. Until now, only two other recorded chronometers from the ship are known to have survived, both of which are owned by the British Museum. The chronometer was also used by the International Joint Commission for the first North American Boundary Expedition (1843-1846) which established the border between the USA and Canada (then British North America) and the 1857 survey of the Australian coastline which saw the naming of Darwin and the Fitzroy River. the full press release is available at: http://www.bonhams.com/press_release/16459/
