Yet another 2593 oddity has emerged. See here
As this is a completed eBay listing which will disappear in due course, it is of a pentagonal black plinth with a fairly typical Sowerby profile of convex curves, slightly bolder than most Sowerby plinth profiles. The seller described its measurements as "40mm TALL / MAX BASE DIMENSION 180 mm / MAX TOP RIDGE DIMENSION 100 mm". As you will see from the listing, I queried the "2593" with the seller, who kindly confirmed that the "number is correct, clear and unambiguous".
So what isn't it? It's obviously nothing to do with Jobling's 2593, their Three Graces Comport
. And as Sowerby are not known for making mistakes with their pattern numbers, it's unlikely to be an error.
So it has to be the plinth for a five-sided item in the 2593 pattern. I've never seen one â€” have you?
Any other views / explanations?
