All I know for sure is that it was made in Germany according to the stamp you say it has on the bottom. Without a picture of the cup, I can't tell you much more than that. It sounds very pretty! The gold detailing is most likely a thin coat of 22ktt gold. I haven't seen a teacup with feet, but when I sold collectibles on the internet, I did tons of research, and there are many places that have a lot of info, if you just keep digging. Keep doing searches with keywords that apply to your cup and see if you can find something similar. Posting a photo of several different views of it will help others identify it for you.
