The faceted blue flower weight is definitely a Perthshire Paperweights item - nothing to do with Peter Holmes.

Could we all please take care that this thread does not become too complicated. We could end up discussing who made the lampwork in all sorts of weights from all sorts of countries and across many many years.
But maybe that would make for a fascinating (although perhaps rather repetitive) thread. If that happens the thread title would be better as a generic "Who made the Lampwork?" or similar.
