Hello. I'm hoping you or someone here can help me locate a part for my Singer Model 31-15 treadle machine. My best friend gave me her grandmother's machine. It's missing just a few parts, most of which I've been able to locate. But the one that eludes me is the table leaf support. It's a curved and tapered metal bracket which attaches to the leaf. When the leaf is raised, the tip with a notch hooks to the iron leg. I see them on one drawer extension tables. My table has a leaf to the left, and one to the back. If you know where I can find one, I would be eternally grateful. Thanks. Ann
