Thank you Grant! That is exactly what the sewing repair shop told me - no way of knowing whether a new bobbin case will work until you try it on the 301. I will just search for a vintage bobbin case. Maybe, this is why Sew Classic quit selling the bobbin cases?

Buying an original would be the best way to find one that would fit and work in your machine, but I would want to try it in the machine first before buying it.
