I have an example very much like yours (but mine is actually a bit neater
). From the base, they look the same, because of the flat polished finish and the very fine chips and colouring of the ground.
I bought mine sevral years ago as "Bohemian". A book by Peter von Brackel published 1999, covers all sorts of European "folk art" weights and he shows a couple with (some) similar features, although of differing design. He attributed them to "Weisswasser 1900-1930", a company in what used to be Silesia.
Whether our weights really are Weisswasser, is speculative at best, but they are of a style which is, to my eye, tidier than most of the "Bohemian / Czech" folk art items from 1900-30.
