It does look similar and may be the same but my perception of the OP's vase was that the blue stripes were darker on the edges, rather than transparent on the edges which is what the Neuwelt stripe looks like to my eye. Do you see them differently? It's very hard to see on pics that aren't really large enough to see detail so I could be perceiving it incorrectly.
There is a long explanation of that piece in Das Bohmische Glas Band II as well.
OP's pictures are too small to really see the detail at all. If you are reading

is it possible to upload larger pictures to a 600x 400 pixels please? Many thanks.
In addition to that though, the shape of the OP's vase is very similar to quite a few shapes by Clichy. I wouldn't have said it was a Neuwelt or Bohemian shape at all. That said, the flacon in the Neuwelt book isn't particularly Bohemian in shape admittedly, but it's much less 'distinctive' a shape than the OPs vase to be fair.
I'm not sure I agree with these comments in the reply above yours though:
Quote reply '
100% Clichy. You will find the whole of the base has been polished to the rim of the base and not just a pontil polish to the centre. 1860-1890.'I have a Clichy jug which does not have a polished pontil mark right to the edge. It's in the middle - and the jug dates to about 1845.
I have another filigrana jug which is often referred to as Clichy but I believe is in fact Saint Louis. That also has a small polished pontil mark in the middle. If I recall correctly Ivo said this was because of the way the canes were held on the pontil(??) or for some technical reason.
Also, the book says of this decor '
Clichy (attribué à)'. So even the book is not that definitive on the decor.
And puts the decor at c.1850
Can't remember what date Clichy closed but will look it up.
