The Towa M bobbin case is the very best for your Gammill. It consistently provides the smoothest thread delivery (and thus the finest results on the quilt) of any brand bobbin case we have tested. Order two! Always have a back up bobbin case.
This high quality bobbin case will also fit many industrial sewing machines using "M" size (1" diameter) bobbins. Please verify the model number fits your non-Gammill machine by checking with your machine's manufacturer. These bobbin cases take the beehive shaped anti-backlash spring. You can preview how to change the backlash spring on our site!
