Greist makes very good accessories for many models of sewing machines. The one drawback to older strait stitch only machines is, well, they are strait stitch only. There are times a zig zag stitch is handy to have such as with edge finishes on exposed inner seams.
The Zigzagger comes with a permanent template for making a basic zig zag stitch and has some additional ones for embroidery type designs to add if you want to change the look. There is a thumb screw for hooking it up to your machine. This is a set of 5 templates and the set screw, as shown in the photo.
Please note that these are the templates only, and not the Zigzagger atachment itself.
The zigzagger includes 6 pattern disks and additionally, when used without a cam, produces a normal zig zag. Despite the title, the patterns all give utility stitches rather than decorative ones although the quality is good enough to be used for topstitching if desired:
