It could (maybe) be a neck chain used by some well to do person for leading a horse or some other animal.

As has been said elsewhere, this item appears quite old so we may never know exactly what it was used for. Could possibly be of Middle Eastern origin???

Another interesting view on it. This would make sense and would explain why the "key" can rotate. And yes, I also think that it could be of Middle Eastern origin. Thank you Stu for your thoughtful comment!
