Stan - I just about was ready to pop a cork....and then I realized you were having a bit of fun. Good one! You certainly got me. Brad

I did mention in a previous message that I saw nothing that even indicated that the photo of Worsley holding the sextant had anything to do with the Endurance or Caird. It could have been taken at some other time in some other place. Anybody find anything that can confirm this one way or the other?
I just found another source that says that the sextant used by Worsley on the Caird is the one in this photograph:
Just kidding - that one's mine.

Brad,Sorry I missed the beginning of this thread or rather the one entitled ‘chasing Shackleton’. I am not really sure where all the talk of the sextant was coming from (or going to) but just happened across a couple of points that I needed to clarify for myself.I think from what I can read, is that you wished to point out that you had a similar sextant to that used on the James Caird. In doing so, you wished to point out that the sextant used on the JC was a Heath Hezzanath Triangle Pattern Frame (frame type not mentioned previously though) as per some photos and as shown by the James Caird Society in their exhibit.I am with you 100% and very happy for you that you have a similar type sextant. And I agree, it makes little difference as to who actually owned that particular sextant – it comes down to who used it and for what.Having said that there were two things that I questioned in my own mind having seen your last posting. Item #7 – already discussed and needs no more explanation. Only thing here is that we see a photo of Worsley holding a sextant……I do not know the origin of that photo or of any statement saying that it is actually his sextant….but I will just assume it to be his until someone says different. That particular sextant appears to me to be a Heath Hezzanith Bell Frame.The other thing that sticks out is you comment, on more than one occasion, that the sextant used on the JC was ‘with all the bells & whistles’. I think you are just referring to the large scope (which is really not so uncommon)……or are there other features that merit this comment?Regardless…..I have no problem with overall drift of the thread (now that point #7 dropped) and apologies for coming in the middle without getting to grips with the actual point of the postings.Kinch.From: NavList@fer3.com [mailto:NavList@fer3.com] On Behalf Of Brad Morris

Subject: [NavList] Re: Beating a Dead Horse (aka Worley's Sextant)KinchIf the picture of Worsley holding a sextant, point 7, is excluded then we still are left with points 1 - 6. Those are the important ones anyway. They indicate which sextant was used on the journey from Elephant Island to S. Georgia Island.I've never much cared who owned the sextant that was used. That's the fine bit of pish-posh that serves no purpose. So Hudson owned it. Did he use it in the navigation? No! Was he the navigator? No!I do care what sextant was used. Its the Heath Hezzanith, with all the bells and whistles, as shown in points 1 - 6. I do care who used it. Frank Worsley. I do care who performed the navigation. Frank Worsley, unquestionably.Thanks for excluding point 7. Your expertise is most welcome in these quarters. It was a weak point anyway. No purpose in including disputable evidence. That only tends to condemn the entire argument.BradOn Jan 18, 2014 7:22 AM, "Brendan Kinch" <brenkinch---.com> wrote:Hi Brad/StanHORSE NOT BEATEN TO DEATH JUST YET!This is the first time that I have seen all the information in one spot. In truth I was not following this thread in the earlier part. Going down through your points all seems clear enough and the evidence is there for everybody saying this information all refers to the same sextant.THEN I came to your point #7 and the photograph of Frank Worsley holding the sextant. (I had not seen this before). Here I have to disagree (I must be careful here…….) that everything comes together.In my opinion all other photos show a Hezzanith Triangle Pattern frame but the photo of Worsley holding a sextant shows him holding (from what I can see) a Hezzanith Bell Pattern sextant.As per George Huxtable in 2009…“I now have a copy of "Shackleton's Boat", by H M Dunnett, who founded theJames Caird Society. That provides a picture of the sextant that they claimwas used by Worsley on the voyage. Not Worsley's own sextant, however; hestated that he borrowed Hudson's (Endurance's navigator) for the voyage,because he found it easier to use on the boat (without saying why).”In my opinion we are seeing these two sextants in this particular thread.When looking at the differences between the sextants note the curves on the frame of the one Worsley is holding. In the exhibition the bottom horizontal frame bar is straight. The swing arm for the magnifier is also different…..look close where the swing arm attaches to the index arm to see the different shape in the arms. One other difference I see is that in the photo of Worsley, the sextant appears to have some sort of shade above the horizon mirror. This may or may not have been fixed but I would suggest it is similar to that on the bell frame sextant in National Maritime Museum at Greenwich. (See NAV1166 or Morzer Bruyns book….page216).I would be of the opinion that on the photographic evidence, Worsley had a Bell Frame sextant and as per that being presented by the James Caird Society, Hudson had a Triangle Frame sextant. (But we do know that Worsley used Hudson’s sextant on the James Caird trip).I attach a few photos….trying to get the angle right (against a dark background) to simulate the photo of Worsley with his sextant……and to show the curves of the frame. The first darkened as best I can, the last just to show the full Bell Frame sextant (although mine does not have the same swing arm as Worsley nor does it have the horizon mirror top shade).Kinch.From: NavList@fer3.com [mailto:NavList@fer3.com] On Behalf Of Brad Morris

Summarizing all the findings1) Seb's site references a sextant owned by Hudson, loaned to Worsley. This information is consistent with the information from the James Caird Society, who state the same. So it references the Heath Hezzanith model without stating exactly that. Unfortunately, Seb provides a link to a generic sextant wiki page , not an image of "the" sextant. http://www.sebcoulthard.com/navigational-instruments.html2) Seb's sight shows an image of the Heath Hezzanith sextant and identifies it as the one Worsley used. This is confirmed by the Scott Polar Research Institute. http://www.sebcoulthard.com/navigational-instruments.html (result: same sextant)3) Flickr image of the Heath Hezzanith sextant, in detail showing Worsley's name. http://m.flickr.com/#/photos/markbrandon/7220573974/ (result: same sextant)4) Image from James Caird Society of the Heath Hezzanith sextant, provided by George Huxtable. James Caird Society states it was loaned to Worsley by Hudson. http://fer3.com/arc/m2.aspx/Fw-Image-Sextant-Used-Worsley-Huxtable-mar-2009-g7574 (result: same sextant)5) Statements from British Museum http://forum.thedarkdoor.co.uk/phpBB3/viewtopic.php?f=6&t=344 and the American Museum of Natural History http://www.amnh.org/exhibitions/past-exhibitions/shackleton/the-exhibition stating that the sextant used by Worsley travels with the James Caird. Said boat owned by the James Caird Society. (result: same sextant)6) image I found on the internet in 2009 of the Heath Hezzanith sextant. Caption in photo states it was used on journey and was loaned to Worsley by Hudson. Person who took photo stated that it was with the Caird exhibit. http://fer3.com/arc/m2.aspx/Image-Sextant-Used-Worsley-Morris-feb-2009-g7412 (result: same sextant)7) Image of Frank Worsley holding the Heath Hezzanith sextant with the very specific star scope. http://fer3.com/arc/img/107418.worsley%201.jpg (result: same sextant)No further equivocation can be made. They all reference the same sextant. The one that Worsley used on the journey is a Heath Hezzanith, the type with all the bells and whistles.Horse thoroughly beaten. Maybe I'll compulsively beat it a few more times, just for good measure. Sooner or later, this topic will arise again and I wanted all the referenced evidence in one spot.My apologies for boring the snot out of you folks.Brad

I believe your sextant matches the one in the photograph, and am happy to trust you that it also matches the one that tours with the Caird!
Unless someone else comes up with something definitive, I am confused enough to consider this beaten horse very much dead.

Subject: [NavList] Re: Chasing ShackletonStanSeb's site is interesting. Its obviously the background information to the Chasing Shackleton program. Interestingly, he never mentions Worsley's navigational log. You'd think that might be of interest. It has been posted here on NavList for years. Maybe he can't decode it.My identification is based upon a tourist photograph of the sextant with the James Caird. It wasn't the best photo but the match was good. The binoculars matched. The frame matched. The star scope matched. Particularly telling was the missing scope (of the companion to the Caird) and its holder. Its a very odd scope. The optics at the far end are twice in diameter that of the near end. The scope stands upright in the box. I've not ever seen one like it (which of course is laughably insufficient evidence) nor its holder.I won't die on this hill. I believe we are encountering specs-manship. Seb points out the sextant used by Hudson aboard the Endurance (probably true). Then we have another sextant used by Sir Shackleton (probably true. But now that's TWO sextants pointed at by Seb, which one is true). Then we have photographic evidence of Worsley holding 'his' sextant. (Definitely true). We know that Worsley navigated the Caird (absolutely true). We have the sextant that tours with the Caird with statement saying this is "the" sextant (probably true). I think the sextant that tours with the Caird, identified as "the" sextant used, matches mine (trust me, okay? Hahaha).So we have a bunch of 'true' statements but only one sextant can be the one Worsley used. I cannot understand why Worsley would switch sextants at the juncture of his most critical journey. He could go with the one he was used to. He could take Hudson's sextant or he could use Sir Shackleton's and experience another learning curve. Why?Seb also points out two sextants, but fails to mention the sextant with the James Caird. Why wouldn't he pick just one. My answer: he suffers from lack of certainty. Everyone wants to have "the" sextant. "Come see the actual sextant blah blah blah". Just like me. I want a match to "the" sextant used by Frank Worsley, especially if its the one used on "the" journey. At a minimum, my sextant matches one that we know he used by photographic evidence. Is it a match the one he used on the Caird. First we have to identify that one!!Brad

Comparing your photo to the on of Worsley holding the sextant, it is still hard to tell if they are the same scopes. However, comparing the relative sizes of the objective lens and the horizon shades, I'd say that it could very well be the same model.
As to whether the flickr photo is Worsley's sextant or not, the photo may be the same as the one at http://www.sebcoulthard.com/navigational-instruments.html. The caption reads "Sextant, pocket chronometer, and pocket watch used by Sir Ernest Shackleton & Frank Worsley during the voyage of the James Caird (Scott Polar Research Institute, University of Cambridge)". It also says
Instruments used by Shackleton & Worsley
aboard the James Caird:‘Heath & Co.’ sextant (owned by Lt. Huberht Hudson, navigator onboard Endurance)
So you be the judge. Is it Hudson's sextant that was used aboard the Endurance, or was it used by Worsley aboard the James Caird? The only place where it says "Shackleton's Sextant and Chronograph" is with the flickr photo, which also omits mention of the watch. The sebcoulthard photo also mentions Worsley, so I suspect the flickr photo only says Shackleton because many more people are familiar with that name than with Worsley.
According to http://www.jamescairdsociety.com/, the Caird is normally preserved and exhibited at Dulwich College, but it has made the rounds. I can't find anything about the sextant being exhibited with it as a rule, even at the Dulwich College site, although when the Caird was at the American Museum of Natural History in New York, "To the stern of the Caird, in a glass case, was the sextant used by Frank Worsley in his incredible navigational feat."

Subject: [NavList] Re: Chasing ShackletonHi StanHere is the sextant with the requested star scope mounted. The optics on this create an erect (non-inverting) image. They are, IMHO, spectacular optics.One must be careful with the online image of "Shackleton's Sextant". He was indeed a licensed master and undoubtedly had his own sextant. In my opinion, it would be somewhat ridiculous if Shackleton did not possess a sextant. However, and this is the important distinction, Worsley was the navigator on the expedition, not Shackleton.. So when the display says "Sir Shackleton's Sextant" it is not Worsley's sextant! Worsley's sextant is exhibited with the James Caird.Brad
