I was hoping it might be a "big one".

I think it is by Paul.
Although the white ground has plenty of holes, it is consistent with other examples. Also, the spread of the twist canes within the weight is very tidy and, to my sense of beauty, well balanced in the placement of the various colours (even if it was just a pick-up of random canes!).
The finsh of the base is one that I have not seen often, if my memory is working properly. But it is clean and precise. Overall size and proportions are pleasing also. And generally it sits well in comparison to another example illustrated by Colin Mahoney in his PY Masterwroks book.
My only hesitation lies in the fact that I have never managed to gather together enough Ysart coloured twist canes to try an analysis of "possible personal twists" for Paul / Salvador.
