Kralik Twin Tube Thorn Vase With Uranium Glass Base.

I thought at first this was by Thomas Webb or John Walsh Walsh but the design, particularly the foot, doesn't match anything of theirs. The closest I've found are on the 20thcenturyglass and kralik-glass.com sites. I think it's Kralik as they used the same sort of splayed base and double vase on other pieces. It's definitely Victorian and is approx. 19cm. tall.
