There are probably many members who might be of more use to you than I, but I will try to answer your questions to the best of my ability/knowledge.
As far as I know "violet" was only ever produced in Chevre Mysore and then in limitedly in some exotics such as Ostrich and Crocs.
As far as the availability of chevre mysore in general is concerned there is some disagreement between the information that has been available to those of us on tPF. Some of us have heard that all chevre (i.e. Coromandel and Mysore) orders have been replaced with
Coromandel Souple and I actually heard that there were some remaining limited supplies of Chevre Mysore, so that one could still order a smaller bag in Mysore.
However, I just had a big mix-up with an order at my store and they may have been extending the availibility of mysore to me as a courtesy simply because of this error. I can't be sure. I only possit this, because no one else seems to feel that mysore was available for this podium.
I hope that this helps a little, and I apologize for my train-of-thought writing.
I actually can confirm much of this based on my recent special orders and personal knowledge. Violet was only produced in mysore. Not in chevre. I have a piece in violet mysore and in ostrich. i also have chevre (not violet of course). (chevre has the spine of course.-mysore has no spine) There is still some mysore but in limited colors violet being one of them--it is only abailable in small pieces in limited colors. chevre is availble as the chevre souple--not being renamed
