Bohemian yellow powder vase

I'd been introduced to this design from a couple of Jericho's posts in the past. And despite thinking the piece may have been Kralik, when it arrived I was less sure, but also intriqued by the observation made in the following post.

Where it is suggested that the shape (in that post) may be Welz. Despite this, the design and décor hasn't yet been 100% identified, as far as I am aware, but all the usual suspects are in the mix. It's a beautiful warm yellow with very dark blue (I think) powder bleeding green at the pattern edges into the yellow of the base. Interesting design this, reminds me of Campanula (Loetz).

A reasonably thick and heavy vase, approx. 8" in diametre similar in height.
