Hi Joe.
I think you are correct that there was not another one in the room: we are talking about different auctions.
I assumed that yours was the one I bid on in a sale on 24 October - but there was nothing else in that lot (I only have an auction house thumbnail of the piece, which I cannot reproduce here for copyright reasons). Although these are very uncommon pieces, two must have gone to auction at broadly the same time. Both had blue/white stave baskets, both were close concentrics, and both use distinctive millefiori canes from a very limited set found only in these pieces. So yours is another member of the group.
I would welcome images for my records if you were able to email them to me. Incidentally, does yours have a flat polished base?
I have attached an image of two examples in our collection.
