For more information on this zig-zagger see my blog on the Swiss Singer Automatic Zig-Zag Attachment.
Google "Swiss Zig Zagger" to see all the glowing reviews about this Singer attachment.
The bight width and length of the zig zag for each of the cog designs can be adjusted giving an almost infinite number of zig zag possibilities.
Straight stitching can be done without removing the zigzagger.
It comes with the ten original different zigzag cogs.
The Bakelite case is in excellent condition.
This original feed cover is a smaller version of the larger buttonhole feed cover. It is smaller in order to fit into the Bakelite case.
There is not a manual.
The attachment not only zig-zags and sews a straight stitch but has feed dogs so that it can be used as a walking foot.
This is the best zig-zag attachment that Singer ever made.
