Kralik pink footed bowl with yellow/red threading and metallic inclusions

So, there, I said it.....Kralik..."so whatya gonna do about it?"
Threaded swirl on bohemian art glass is most often seen against a tango ground, reds, yellows and blues predominantly. And we have had some discussions on here about attributions, but I don't think any of us have really come up with a maker.

All the usual suspects are there, but nothing definitive. Interestingly there has been a yellow ground small posy vase with a metal frog on ebay (us) for a few weeks, may have finally gone now, but that was a very similar pattern and had the classic 'czechoslovakia' arched mark, which we attribute to Kralik.

There's a very long thread to a post on this subject here: https://www.collectorsweekly.com/stories/251241-large-bohemian-art-glass-lidded-jar. This link is quite important, because the vase here has very similar threading, colour and 'flow-style' as the one in the link.
This vase proved really hard to photograph, so I tried in a few different conditions so as to pick up the pattern.

It's a stunning piece, despite the fact I have spent more time here trying to show the threaded pattern rather than just photographing what is actually a very beautiful vase, a little fussy, but beautiful all the same.

Stands 6" (15.5cm) + nice polished pontil and excellent base wear.
