In very fine condition for this rare accessory, this is the 3rd one I've had in the last 3 years and only the 7th I've ever seen. I have been told by author Robin Rapley that there are probably 12 or fewer examples in collections and museums. Condition-wise, this is the second-best example I have ever seen. At 155 years old and having seen heavy use, this one is outstanding with minimal wear, nicks or dents.
