<P><b><center><font color=blue><font size=5>PRINTED USER INSTRUCTION</center></font></font><P>Authorized reproduction of the manual for Singer sewing machines of the classes 15, 66 and classes 101 and 127 are briefly touched on. It was designed for students to use as all of these models could have been found in their classroom. This manual is dated 1935 so from this era the heads may have been found in a treadle base or more likely as electric sewing machines. It has basic information on these models, covers most of the attachments, has cleaning and oiling and some troubleshooting information which applies to all of these models. In other words, it is like four manuals combined into one booklet.
