it's a minefield out there

I've not seen this vase, but I have seen a vaguely similar vase attributed variously to Webb's, Harrach and Boston and Sandwich

- it's the same piece on each of the three different sites

I'm coming down on the side of Bohemian and possibly Harrach

They seem to have done a similar shape as the body of the vase, the wishbone feet and the way they are applied are a possible (I can't find anything the same on English glass or French glass) and the blue colour glass fits.
However I've not found a similar crackle/overshot or a rim that is definitely the same or the same type of thing.
The only piece I can find a similar rim on is an Auguste Jean vase, which I am pretty sure mine is not as nothing else about my vase fits. Anyone have any ideas who else may have done this same type of rim? I can find lots that are zig zag rim trails like the one Greg posted above,but none that are this kind of applied drip with the zig zag top as part of it.
thanks for any ideas
