Centaur II Bobbins
Hi, I picked up a baggie of these Singer Centaur II bobbins from a thrift store plus some feet also. Never have seen these kind of bobbins before. Does anyone know what kind of Singer sewing machine they work with. Newer fancier machines or older ones? Thanks! It says on package exclusive metal spring...bobbin winds in place for ultra unlimited or stylist. Tried to find online with no luck.
