1. Non-Stuart glass in the Stuart collection.
At least two pieces, the magnificent and much repaired Walsh "Opaline Brocade" epergne, and the Walsh "Water Lily" table centrepiece, were certainly not Stuart.
2. The vase in Hajdamach 1, plate 258.
I have one (which I will have on display tomorrow), slightly smaller at 11" compared with 14.5" in the book, otherwise identical. The peculiar top of these is identical to that on a vase that Gulliver has identified as Stuart from the pattern books — the only difference being that Gulliver's vase was shorter and squatter. I've seen nothing in the continental glass links that looks remotely like this eclectic vase top. So the vase in Hajdamach 1 is Stuart.
Take care with the date of Stuart's "Peacock Eye" patterns. I know that circa 1910 onwards is now thought to be more realistic.
