    Re: Sextant with Ivory Scale, Serial No 577 by G. A. Berry & Son, Hartlepool,

    David,

    Many clocks, sextants and the like, including marine chronometers, bear the name of the retailer rather than that of the maker. The "maker" of sextants in the nineteenth century seems as often as not to have been the assembler of standard parts made by others in various cottage industries. At the heart of the sextant is the divided frame and most of the dividing engines were in London, perhaps a dozen in all. Specialist founders produced the cast frames which were then finished and divided by makers.

    I have owned two sextants practically identical to the one shown. One was named E and E Emanuel of Portsmouth, a jeweler and retailer,  and the other was un-named. I was persuaded to part with the former and still have the latter. It can be seen in the posts for 10 Nov 09 and 17 Dec 09 at www.sextantbook.com. Ivory was probably cheaper than silver, but it tends to shrink and tear free from its moorings.

    What is NavList?

    NavList is a community devoted to the preservation and practice of celestial navigation and other methods of traditional position-finding. We're a group of navigators, navigation enthusiasts and hobbyists, mathematicians and physicists, and historians interested in all aspects of navigation but primarily those techniques which are non-electronic.

    To post a message, if you are already signed up as a NavList member, start a new discussion or reply to any posted message and use your posting code (this is a simple low-security password assigned when you join). You may also join by posting. Your first on-topic messsage automatically makes you a member, and a posting code will be assigned and emailed to you for future posts.

    Uniquely, the NavList message boards also permit full interaction entirely by email. You can optionally receive individual posts or daily digests by email, and any member can post messages by email (bypassing the web site) by sending to our posting address which is "NavList@NavList.net". This functionality is similar to a traditional Internet mailing list: post by email, read by email, reply by email. Most members will prefer the web interface here for posting and replying to messages.

    NavList is more than an online community... more about that another day.
