Helen,
Listen to Muv. She knows her stuff when it comes to long bobbin machines. Those are her favorites and she has sewn with them for a while. You can still find those long bobbins on the internet and Sew Classic. com has them also. They are in Ohio and ship quickly. Jennie knows her bobbins and can help you get them. Needles may be harder to find. Your machine is beautiful and in good shape cosmetically. Keep her forever.
