Oh dear, I am getting foggy.
It is a 1930's Nazeing Glass Funnel Vase No 37/55. The decoration is called Lattice effect.
These are considered rare because what ones have surfaced are not well recognised. Should do well if you wanted to sell. But no idea how much, it depends on the audience.
Could I use the images for the site please? I am building a page of Nazeing images to go with the article.
You can see your shape in one of the catalogues showing in the article LINK
although not with this decoration. That URL will be changing soon to ysartglass.com
