First, thank you to everyone who posts on this board, I have learned so much about vintage machines. I have a singer 237 fashion mate that was given to me by my mother-in-law many years ago, and a singer 347 that belonged to my mom. I decided that I wanted to start sewing on these 2 machines (I also have 2 newer babylocks and a middle aged Kenmore model 17860), because I want to try to put them in cabinets and use a knee lever controller with them. I am not sure if I have the right bobbins for the 237 and the 347. I have some metal bobbins but I think that they go with the Kenmore and I do not know what class they are. Is there a way to identify bobbins - like whether they are a class 15 or a class 66 or something else? If the metal bobbins fit in the bobbin case, does that mean that they are the correct type of bobbin for the machine?

Cari, thank you for the information. The Kenmore is a series 158 machine. The Singer 237 uses the removable metal bobbin case that fits in under the machine so that would use the class 15's and the singer 347 has a drop in bobbin so then it would use the class 66 bobbins, per you information. The Kenmore metal bobbins are straight sided and they fit in the Singer 237 bobbin case so I will try those in it. Have to see if I can find the bobbins for the 347, I am sure I have some around here somewhere. Thank you again for the information!

Not sure if this applies to your machine, but I found that with my 99K, I had to track down original vintage bobbins. The new size 15's I bought did not fit on the winder at all, and caused all kinds of issues with the stitches. Once I found the vintage bobbins, she sews like a dream!

The 66, 66K, 99 and 99K machines take a class 66 bobbins.
