Pink zipper trophy shape vase

I must apologise for the light- we are entering Autumn in the UK this week!
A pink brick/zipper décor trophy form vase with a ground pontil mark.
I think that options are open as to maker but Victorian experts are welcome to posit answers!
It is a more delicate form than any Welz trophy but I wouldn't be surprised if it were Welz, or Harrach or similar.
If we were guessing a maker for an unusual piece, it would have to be my usual - unknown!
It is 16.5cm high.
