Gents,
Thanks for this interesting developing! Although it didn't answer my question, I found it as a good lesson!
I am not sure, if "my" piece shown is a private purchased one or a heavy worn version, while losing the enamel or painting.
One Turkish collector mentioned, that this could be a “unofficial” Turkish made version for the daily wear, while the official (enamelled / painted) stayed “at home”.
Well, I do basically could hardly believe this comment, as I would expected more pictures / pieces. But on the other hand, I have no counter-argument
I guess, it'll stay a mystery…
Thanks and regards,
Chris
