i'd be very surprised to see a harlequin go for anywhere near £185. These pieces can be stunning but the top end even with a H cane would probably be 120/140, weaker less interesting and unsigned examples nearer 70/80. Caithness and Selkirk examples less than half this level. The Ysart examples were made in relatively large numbers (along with fountains) compared with some other designs made by Mr Ysart Esq.
