Has anyone ever seen one of these before? I found it in an antique shop for $8. It's called a Spin-Fix and says Made in Germany. It sits on top of the clamp and spins. The arms are adjustable although they're next to one another rather than in a cross design like the swifts we usually see. I'm sure it's a yarn swift. I tried searching online for any information but no luck so far. Not sure how I'll use it but it was a fun find.
