Hi Mike,
Thanks for the info - it's a shame to hear that it's not a known colour/ variant of this pattern, but it remains an interesting piece nonetheless. Looking at the detail and spacing of the leaves, and also the overall proportions I did feel it looked like an exact match (albeit flanged into this open shape), so much so that I was wondering if it could have been a trial piece or a special order. But of course it's hard to tell from the ebay photos and the lack of a mention in Marcilhac would tend to count against this. Still I'm looking forward to it's arrival & will post better pics when it arrives. Even as a copy/ similar design it is of interest as I've never seen another example.
