Candace,
No thread cutter on my machine. Yes, it is the proper width. The one that I had that broke was a Singer that I picked up at a garage sale, and it worked fine. I plan to keep looking at garage sales and buy anything I find in a short shank walking foot until something works better. Right now whenever I need a walking foot, I use my 301 with a Singer walking foot held together with a rubber band -- I think it came with one of the 301's. I know that the 301 has the narrow feed dogs, and this walking foot shouldn't be effective, but works for me.
I would appreciate any information you find, Candace. Thanks!
