Singer Adjustable Zigzag Attachment - Silver

Expand the capabilities of your vintage Singer sewing machine with this lot of two classic Adjustable Zigzag Attachments. These clever mechanical devices allow a straight stitch machine to create variable zigzag stitches for decorative effects, applique, or finishing seams. This lot includes: Singer Adjustable Zigzag Attachment (likely Part #121706): Comes in its original smaller green box with the instruction manual (dated/marked 121706). This attachment allows you to adjust the width of the zigzag stitch. Singer Adjustable Zigzag Attachment (Style appears similar to #161157 or similar): Comes in its slightly larger tan and green original box. This is a different model but performs a similar function, allowing zigzag stitches on a straight stitch machine. Compatibility: Both boxes indicate these attachments are for use on "'Singer' Lock Stitch Family Sewing Machines." This typically refers to vintage Singer low shank machines (like the Featherweight 221/222, 15, 66, 99, 201, etc.). Please verify compatibility with your specific machine model before purchasing. These will generally not fit slant shank or high shank machines. Details: Brand: Singer Manufacturing Co.
