The flower lampwork is pretty much the same (except for the central cane) as in
Example 06 shown in my page of example fake py weights. There are, however, a variety of different lampwork styles across the range of these items.
And the direct answer to Sue's question about who made the lampwork is that, amongst collectors, we do not know.
Although similarities may occasionally be seen with lampwork in other weights, such things cannot be taken to mean that a particular person produced all such elements. This is easily shown by comparing lampwork elements in genuine Paul Ysart weights from his 1970s period, where much of the lampwork was made by his apprentices but was of a form and quality very much like Paul's own work.
