Hi Alan,
I have a Clichy concentric on a turquoise over opaque white ground which has a diameter of 1 3/4ins. and cannot have been repolished much if at all, as not only is there none of the white "lining" of the ground to be seen but it still has that typically Clichy indented "ridge" around part of it.
The weight on eBay appears to be a purple over opaque white ground and there does not seem to be any of the white showing through, which would seem to indicate little or no repolishing.
In a larger size I have at a Clichy with canes positioned down the sides and which still has this ridge, indicating no repolishing and so I have feeling that Clichy may sometimes have used this positioning of canes as a decorative effect. In much the same way as they sometimes positioned canes in this manner within their newel post finials.
The eBay weight is v. pretty, pity that it's been through the wars.
Nicholas.
