I bought the piece several years ago from Ken Richards in sydney, Australia. At the time, I think he was upgrading his collection, and was selling a few of his pieces. I note he no longer has anything for sale on his very nice website. It was pricey, at least for me, but not as high as what I see shako plates are commanding these days. I can only drool when browsing Bertrand Malveaux's catalogue. Maybe I can scrape enough up for a button or two.
