Vintage ? Sewing Machine Cam Identification
Hello... I have a case of sewing machine cams, but have no idea what make machine they're for. There is no brand or markings to indicate a manufacturer, no text - except for "stretch stitch" on one cam... nothing to identify what machine to use them on. There are graphics on top of the cams, I assume to identify what type stitch they are, nothing inside or underneath. Is there anyone who might have an idea what machine they'd work on or how I'd go about finding what machine they'd work with? Thanks for any suggestions anyone might have.
