The age of Hughes’ sextants has come up before.  Might it be useful to start a list of arc numbers v date of original certificate in the Resources section for the convenience of new purchasers?  Mine is 25410 and the certificate is dated 28^th February 1941, so they must have produced quite a lot of them.  Others supplier’s overhaul certificates can also lead to confusion.  The attached link  http://www.the-saleroom.com/en-gb/auction-catalogues/andrew-smith-and-son/catalogue-id-srandr10010/lot-6ace42ba-0689-4eef-814a-a3f900c5bb4a  shows a sextant advertised recently as a post-war sextant by B Cooke & Son, Hull   when close examination of both the sextant and the writing on the Cooke’s Certificate shows it to be a Hughes three circle Mates sextant. Its number puts it around late 1940.  DaveP
