Red and white - gotta be Kralik?

This was bought from the US. I was attracted to its milky opalescence and the red and white spoke Kralik to me.
It has a rather messy acid stamp on base - which I am wary of. These can be added later to add supposed value.
The rim is ground but not polished, and plain, not chamfered.
So putting my doubts about the mark to one side, I think it represents a Kralik Deco product. Any thoughts from the great and good!?
It is 16.5cm high.
