Pam says: Looks like a type 15 bobbin. Gobs of machines use them!
Linda in Va. Beach says: This looks like a 66 class bobbin, for the Singer 66, 99, 201, 185J and K, Spartan, etc.
Louise says: 201 bobbins
Linda from Oxford, Ohio says: a class 66 bobbin, used in a slew of Singer machines, including the 66, 99, 185, 400 series, 500 series and probably more.
Bonnie says: These are No. 66 bobbins. Fit Singers 66 (Red eye) of course but also a host of their later machines 400's 500's, etc.

Add your comment here. This is definitely a class 66 bobbin - you can still buy them new in metal and plastic. Many sewing stores carry them.

Tasha says: that is a class 66 bobbin. My Singer 201 uses them and my Janome Memory Craft 9000 uses the clear plastic version. The plastic ones also work on the 201. I am pretty sure that quite a few machines use them.
