We order all kinds of bobbins from Brewer Sewing Supply. The part numbers are #2518NS Bobbin Singer 15 class metal grade A and #2518T Bobbin Singer 15 class metal economy. The #2518NS are smoother and a little better made. You can probably find them online. We sell them for 40 cents each or 10 for $4.
