For some of the more unusual items, it can take some time (and sometimes many months) before a positive Id is found. For really obscure pieces, queries from years back have still not been resolved.
Although there are many knowledgeable folk using the GMB, not everyone looks in constantly and we certainly do not have all the world's experts looking in! Also, there is never any guarantee that anyone else will have seen a particular piece or its design elements or decorative features.
Most folk refrain from simple comments like "Sorry, I don't know", so it can often seem that hardly anybody has even considered a request. For myself, the only thing I could say about this piece is that the decoration looks like 19th century Bohemian ... but that probably does not add anything to the Id as "Moser" has already been considered.
