This is a great treasure!!! The attachment on the left front of the box looks like the attachment that was my grandmothers. She still had the instructions for using it and I have found that it works on my Elna, Paff, and White low shank machines. I have made some "perfect pleats" with it. Several months ago (and it was a re-run at the time) Simply Quilts featured a lady who had an extensive collection of these old machines. She did a demo with several of them and spoke about how she had gotten them cleaned up and useable. While visiting my daughter in Alaska, I learned that there are areas where there is no electric power and the women in these areas are using these old machines to quilt.
