Hi,
These have been around for a lot longer then ten years. I bought one from the same series back when I was a student - so given that it was second hand then, some 36 or so years ago, I doubt any connection with Chic Young, P/Ps, etc. In fact they've been around all the time that we've been aware of the infamous 'cellophane' glass.
More abrupt change between the rim and body colouring; enamel granules and separate colours quite distinct; and a nice polished pontil; are all distinct features that are not commonly found on Monart, Vasart, Strathearn, or Perthshire Paperweight's vessels. Oh and none of the shapes are consistant with the Ysart shapes - again similarities may be found, but are outweighed by the several that aren't right.
