My neighbour gifted me with a Kenmore 12912 machine purchased new in 2001. I think she had it out of the box two or three times. Everything is there but it only has two bobbins. I've read the manual from cover to cover and no where does it say exactly what bobbin it uses. I know Kenmores were made by Janome so will the bobbins from my Janome 6500 fit or do I need something else? I'm sure someone on this board will be more helpful than that machine booklet.
