What Makers mark has a swan with a crown?

Answer:
Look! There are millions of manufacturer's marks. For starters you do not even say what object the mark is applied to!! If it on a piece of antique porcelain, then you need to buy a book of porcelain marks or borrow one from your local library. Or, whatever.
