Hi Anne,
Thank you for the warm welcome!
Glad I'm not the only one stumped by this one. No, mine doesn't have any identifying marks, nothing is written on either of the tabs, or anywhere else that I can find.
I wasn't sure mine was German in origin until you gave me that link. I wouldn't be too surprised to find it was Walther; but I've looked through most of the Walther/VEB Sachsenglas catalogues I've found online, and I haven't found it yet...
Summary: So far it appears we know of two sizes, that they come in a fish version and a mermaid version, and that there are two or possibly three colours. I say possibly three colours as there was a listing on ebay.ie, and the bowls look pinkish; but they've described them as green - I'm not sure whether that's a white balance issue or their real colour though. Mine is definitely blue.
