That group goes from 2.5" to 8.5".
I did get another more complex one recently which is 9" - it's got a clear, sort of exploded open mushroom case bit at the bottom - the same (but individually different) as the taller one in the image on the page facing the Contents list of Hajdamach's 20th Century British Glass.
If you want one, just ask Ed. His normal mushrooms are not expensive, he's really friendly. When I first saw his Wizard cone lamp in the Scottish glass Society Exhibition 2000, IT WAS SOLD! :thud:
However, not deterred, I got Ed's telephone number from the Exhibition organisers and just called him up to ask him to make me a couple of them, which he duly did and sent them to me.
Michael and I have even been to visit him - which was great, and although glass didn't really feature in the conversation, this meant M joined in a lot. Ed has many interests.
