Czech Art Deco tango urn with applied flower

It has a generic brass frog with a rim diameter of 9cm. This is a ribbed, flower urn in the same mould (figuratively, not literally) as a stem vase I have and several pots Anne Landers has posted.
We would have said Kralik with some confidence 2 years ago but I am less sure now. Of course, they might end up being, but I don't think the links are all there just as yet.
The very fine cased glass mimics the trefoil jugs and jugs with high handles, all of which remain "Anonyme" at the moment, albeit with tantalising décor and shape links.
This is 12.3cm high. The vase's rim is 8.5cm but it comfortably fits the generic frog mentioned.
