Vintage sewing machine darner mender button holer original box instructions

This is a vintage darner. It comes in the original box that says you can use it for quilting, appliqué, mending, zippers, buttons and making button holes. This comes in the original box with instructions but no machine spiral attachment. Also included in the box is a button hole gauge paper. I could not find who made this. The circle darner is about 3" in diameter and has a few rust spots. The fabric is held in place with a rubber band; a new rubber band may be necessary for continued use.
