There are several possibilities for this type of weight, although I am only familiar with a few (i.e. I've seen a couple in real life and a few more in books). Mostly from studios in the 1970s / 80s.
Depending on the actual "colour" of the glass, it might be:
- Midsummer Glass (former English studio)
- King's Lynn / Wedgwood (but I don't know whether designs like this were made after Wedgwood took over King's Lynn)
- Langham Glass (studio of former King's Lynn man, Paul Miller)
It could also possibly be Selkirk Glass (but again, I don't really know that they made exactly this type)
Another option is modern Chinese, with some of their examples being pretty good, too.
I would be pleased to learn of other makers for this type of weight, as I have not collected this theme myself and my knowledge is slim.
