... Harlequin, Fountain or ? name ...
There is a lot of confusion about the names for these types of weight.
Paul Ysart called them "Harlequin", "Double Harlequin" or "Triple Harlequin" depending on the number of layers. This naming was carried through to his time at Caithness and then later at his own studio at Harland. Caithness continued with that naming after Paul had left (but I do not think they produced a Triple version).
Paul Ysart made them with one central and four outer bubbles (early years only?), and also six outer bubbles and eight outer bubbles. European examples of similar design (19th and early 20th century) can have five or seven outer bubbles as well as four, six and eight, and they are usually referred to as simply "frit and bubble" weights
Strathearn Glass also made a similar looking weight, with 1,2 3 and 4 layers within their "Arctic" range and called them "Force 1" (2, 3 and 4). I believe all of these weights had four outer bubbles and a central bubble over the cane layer(s).
The similar design made by Perthshire Paperweights and also John Deacons in his own studio, was / is, I believe, simply called "Aladdin's Cave". Or, more accurately, for the Perthshire examples "Aladdin's cave" was the name in early literature but later, "Fountain" was used. The Perthshire examples had either two or three layers. And maybe (??) all of these always had a central plus four outer bubbles. [If somebody knows for sure, please add a post].
The "Fountain" design of Paul Ysart is something different. It has a single scrambled cane base (with or without twists) but does not use just bubbles as the upper decoration. Instead, it has filigrana twists pulled down near the edge of the dome and with a single air bubble over the centre of each "arm".
Too many EBay sellers cannot seem to ever appreciate the distinction of these names, even if I tell them!!
