I inherited a vassar treadle sewing machine and was told it's from the late 1800's. I've research sewing machines and cannot find anything on the "Vassar" brand. Thanks!
According to my Charles Law (a wizard on antique sewing machines) your Vassar treadle could be made either by the Standard company or the National Sewing Machine Company. If you can post a picture, I might be able to identify it further. MaClark
