I would like to see a couple more photos ...
a) Base photo again but with pontil scar in focus (use the camera "flower" icon for close focus)
b) Close up of all canes (close focus again showing one section with each different cane type in view)
I think this is likely to be from the Ysart Brothers period and quite possibly made by Salvador. But it seems to also be an example that shows some of the problems of attributing Ysart-style weights to one particular branch of the family.
Edited to add: What is the size of this weight (diameter and height)?
