The decal is a harp playing mermaid. The badge appears to have 3 buildings (mid-evil, Russian?) or it could be 3 chess pieces, then there is some kind of long swirl across it that might be a rope or lion's tail. It's definitely not a Singer Badge I'm familiar with.
Singer 12 type shuttles are $60.00 each and hard to find, by the way.

edit: On second look, it appears to be a woman holding a ship anchor rather than a mermaid, but it could be mistaken for a mermaid with a harp.
