My guess is that this is about 100 years old European origin piece, but I am not sure where to ask for help. I am from Serbia and this piece is a family heritage.
Wow, nice catch! It took me 5 minutes to find two similar Schramberg marks here: http://www.porcelainmarksandmore.com/germany/baden/schramberg-01/index.php
Now I can try to identify the piece and the year it was made. Thanks a lot!
