Commodore Anson & Hadley's octant

Hello . Did Commodore Anson have an octant aboard HMS Centurion ? I wrote it in the chapter "Consequences : naval improvements" of the WP:fr article "Le voyage du Commodore Anson" , because on the frontispice of the book, under the engraved portrait of the Commodore, at the right of a view of the battle between HMS Centurion and Na. Sa. de Covadonga stands a nicely exposed octant, obviously not an old Davis quadrant...The only clear reference I found about any such device is the old one they found on Tinian. Thanks for your answer . signé Arapaima , 2008/11/29 (looks my old iMac can't have me loged in , I try again...) —Preceding unsigned comment added by Arapaima (talk • contribs) 10:24, 29 November 2008 (UTC)

It's likely but I can't find any reference to it. I checked Richard Walter's ANSON'S VOYAGE ROUND THE WORLD (free from the Gutenberg Project) and Sir John Barrow's Life of George Lord Anson (full text at Google books) and neither mention anything.

Since the Hadley instrument was use for roughly 9 years at the start of Anson's voyage and his was a high-profile mission, he would likely have been equipped with the best instruments and had officers schooled in the latest techniques. --Michael Daly (talk) 19:44, 29 November 2008 (UTC)

Thanks a lot, Michael...--Arapaima (talk) 10:56, 11 December 2008 (UTC)
