Probably not so close, but the best I can find based on your sketch is Fireside Chat NF by Nick-Curtis [2003]

Interesting idea, a swirly font that combines a swirl with a ball terminal at one end and a plain swirl at the other end. Here are two fonts that give you your choice of these two effects. Janda Hide And Seek http://www.myfonts.com/fonts/kimberly-geswein/janda-hide-and-seek/ and Emploi http://www.myfonts.com/fonts/paratype/emploi/ Emploi might be more to your taste than Janda Hide And Seek. If you can tinker with fonts Emploi could be edited to give it balls where you want them.
