Ok, first of all, I will say ... I have the weight by my computer. (Quickly paid for and quickly delivered by the seller.)
I was fascinated by the coloured chips / bits and the way they were neatly formed to construct the ground. And I was also fascinated by why nobody was prepared to bid! I had my doubts about it to begin with, but the more I looked at the photos, the happier I was that it was an ok Salvador Ysart weight. My reasons were:
1. The "fountain arms" are made from thin, translucent twist canes and that feature ties in with others that have been attributed to Salvador on various visual aspects. I have yet to see a Paul Ysart "fountain" weight that has thin, translucent arms like these. ( * )
2. The coloured chips reminded me somewhat of the ground in another Salvador weight I have, which includes some distinctive "Salvador canes".
3. The base is finished with a quite neat, but still uneven, ground out pontil area
4. There is pitting around the outer parts of the base. This is a feature that occurs a great deal in Salvador's "3D Butterfly" and "Upright Flower" weights, as well as in many other weights most likely from the Ysart Bros years.
5. And now that I have it, it is clear, when viewed in profile and with transmitted light, that the dome is full of wreathing. Not a feature found to any great extent in a Paul Ysart weight.
( * ) For those with access to copies, please see the PCC 2013 Ysart Exhibition Catalogue, page 92 for four examples of Slavador Ysart "fountain" (or "carousel") weights. And also Bob Hall's Scottish Paperweights book, page 51 for another example.
I was certainly interested in this weight for possible comparison to other "coloured chip / bits" examples that may, or may not, be Ysart items.
