Authorized reproduction of the users / instruction manual for a Willcox and Gibbs Automatic Noiseless sewing machine with many of its attachments. It is a chain stitch sewing machine, which means that it sews with only one thread. A looper catches the top thread and the stitch is formed. It does NOT have a bobbin. It has basic information and much more. This version of the sewing machine was operated either by electricity, a treadle or a hand crank.
