Yes Leni - they are very much alike. Perhaps we each have one item from a full multi-piece set?
Not likely I'd say

because
the opalescent trumpets are different to the rest.
whereas mine are, in the case of this particular piece, the same glass as the rest! Which just goes to prove what I was saying about how I've found very different glass apparently used in very similar pieces!
I would love to have your technology when illuminating my Uranium glass! I only have the most basic LED torch!
Having seen yours I think I agree my 'broken triple' would also have had a plain 'trunk' in the middle rather than a third trumpet, but who knows? There is such variation in these pieces!
When I spoke to Mervyn Gulliver at The National last year he seemed to think that many of the Stourbridge glasshouses would have made their own versions, which the different types of glass might indicate - or perhaps not, if they were made over a period of years :huh:
Oh, it's so confusing! With the exception of some, like those shown in my third and fourth pictures, which can possibly be 'matched' to known designs, I think I'm going to have to settle for 'Generic Stourbridge'!
