This one wasn't TOO expensive off ebay, there are so many of them there that sometimes one slips through without too much attention. Dern, I thought I had a different idea, nothin new under the sun. (Not like I was inventing anything) One thing I thought about, is it will also help in bobbin winding some of the treadle heads, I could even use it as a dedicated bobbin winder. I have a few BWs lying about.
