returned to Greenwich 7 November 1836. After a period at Arnold and Dent for cleaning it was transported by HMS Lightning to Devonport or Portsmouth for issue to ships there. It was returned to Greenwich 17 November 1841 and after another service by Arnold and Dent was issued to HMS Formidable on 13 January 1842. It stayed with Formidable until 20 November 1845 when it was returned to Greenwich. It was then serviced by Charles Frodsham and sent for issue to ships at Portsmouth. It was transported back to Greenwich periodically by Royal Navy ships for service by Frodsham (HMS Rattlesnake 11 March 1850, HMS Odin 27 December 1854) and finally returned from Portsmouth 7 May 1857. The final ship to be issued the chronometer was HMS Pembroke who received it 20 April 1858. Pembroke returned the chronometer to Greenwich 1 February 1867.Greenwich ledger, pp.165,1126 Use on shore After serving on Pembroke the chronometer stayed with Frodsham for over six months. Greenwich issued it to the Meteorological Committee of the Royal Society on 25 November 1867. The Meteorological Committee used the chronometer for observations at Falmouth Observatory. It was returned to Greenwich on 3 November 1886 and sent to J Poole for servicing 22 November 1886. Poole returned the chronometer on 13 December 1886 declaring it to be beyond economic repair. It was given to E. Dent & Co. on 16 July 1888 in part exchange for the chronometer Dent 43107. It was later acquired by the private collector Courtenay Adrian Ilbert. After his death in 1956, Ilbert's collection was put up for auction in 1958. The auction was cancelled, however, and the collection purchased by the British Museum following a private donation of funds.Greenwich ledger, p.1126 BBC Programme The chronometer was object 91 in the BBC Radio 4 series A History of the World in 100 Objects, first broadcast 11 October 2010.
