I don't recognise the inner canes or the darker ones in the star arms. But the others are certainly early Ysart canes. The yellow-with-dark-centre cane can be found in both Paul's weights and some from the Ysart Brothers Glass side of the family. The multi-coloured "fence" canes [my personal description] are known in many Ysart Brothers Glass items.
The thin, mottled white ground (almost invisible until viewed under enlargement) is also known in some Ysart Brothers pieces. The setting of the outer canes is very good, but the slippage in a couple of the star arms does lessen the appeal (to me, at least).
So my guess is that it was made by Salvador during the Ysart Brothers time. [It is also feasible that it might have been made by Salvador in the 30s - or it might have been made by one of the brothers in the Ysart Bros time!]
