some Pantin weights with Millefiori you can find at page 24, (Figure 19, 20, 21), page 25 (Figure 22) and page 26 (Figure 23) of the 2005 PCA Bulletin. There you also find the very interesting Article from Paul Dunlop.
Figure 5 on Page 20 has the same parallel filigree twists, like my mystery weight. The rose shown in Figure 9b is also very similar to the one in my new weight.
The miniature Roses in the yellow canes may be a hint for Clichy but the flat polished base without a basal ring could be more a hint for Pantin.
I saw some VSL weights, but they never had such great canes like this weight.
The shape of the weight is very unusual for bohemian pieces, also his size and weight, as it is very heavy. At least, the canes are too perfect for bohemian weights.
I´m very unsure between Clichy or Pantin. Hopefully Paul Dunlop can help
Have a nice Saturday!
