Authorized reproduction of the users / instruction manual for an Eldredge Guaranteed Two Spool sewing machine. It uses an entire spool of thread in its bobbin case, which makes it rather unique. Eldredge sewing machine needles are recommended for it so it was made by them and National bought the Eldredge Company so it applies to the National Two spool machine too. There is basic information about the machine, cleaning and oiling and some troubleshooting information. It is shown in a treadle base and has extensive parts information in it.
