Authorized reproduction of the users / instruction manual for a Singer Medium, model 13, a transverse shuttle sewing machine with many of its attachments. The manual has basic information and some troubleshooting information. The head illustrated in this manual is slightly different mechanically that the one in smm096 and the written information in it is slightly different too. The model 13 is very much like the Singer New Family, model 12, only the arm is higher and the bed is longer so there is more clearance for maneuvering fabric. Because of this, some people consider it a semi industrial sewing machine. This original manual is circa 1880 and is very hard to find. It is in excellent condition so we have high quality reproductions of it for you. They are very easy to read.
