An original Bobbin Case is by far the best, so be sure to view many of our little replacement parts and screws should your Bobbin Case just need a part or two to bring it to top running order.
However, in the event that your bobbin case is missing or completely defective, know that we personally test, calibrate and include a stitch sample with each one that we sell. The word SIMANCO will appear on the inside or outside of the bobbin case if it is an original (consider all others a replica). All of our original bobbin cases are vintage parts, taken from original Singer Featherweight parts machines.
