I too have No idea.
I can see what you mean when you say it kinda has that Czech look to it -- the colors, and the way they are done. The foil, well I do not know enough about that. It *does appear to be well made, and has some really good weight to it. As you can see, there is wear to it.
The top opening is not wavy, I just took the pic crooked.
Hmmmmm....this might be a long one to figure out
Just have to keep a look out as we travel the Net for something kinda the same, or a lead in some direction...
