The garland canes match ones seen in many early Vasart weights. The form of ground, with a single or double row of canes around a central colour (or sometimes a scramble of cane chips) is also seen in many of the "3D", or floating, butterfly weights that have the body of the insect pushed down between the wings. And the same style of ground is known in a numer of "Upright Flower" weights. Most of those weights are of a similar size being around 3.5 inch diameter and 3 inch height.
In lots of those weights, the base shows a lot of "pitting" around the outer portions and may have a roughly (or sometimes very smoothly) ground pontil area or perhaps a "crunchy" snapped off one.
The final setting of the canes often looks quite "loose" or downright "scrappy", with only a few that I have seen being very well controlled.
All the above leads me to believe that these "carousel" weights, as well as the upright flowers and 3D Butterfly ones were made by Salvador Ysart and most likely all in the mid-40s to mid-50s "Ysart Brothers" period.
Values vary according to the actual size of the weight, the degree of neatness of the cane setting and the colour balance of all the canes and twists. But even the not-so-well-set "carousels" can get some collectors reaching into their wallets for upwards of £150.
However, there's a fairly neat one in the "weights-n-things
" site with a retail price of Euro 445.
I saw a really good example of a Salvador "carousel" weight yesterday, but it was not for sale.
