I would help to know what model of machine these come from. Some old machines didn't do anything more than straight stitch. I could be wrong but it looks like you might have a cording foot, a darning foot, a ruffler, a zipper foot (maybe more than one kind?), a special zig-zag foot or applique foot... Do any of them have uneven bottoms, etc? I just realized, I know a more about sewing than quilting which is a really funny statement. I am so new to quilting it takes me forever to complete a block.
