All the machines I found today, save one, were in pretty bad shape. When I moved the wheels, they didn't sew freely. Only one still felt like precision movement when I turned the wheel. Any of these badly needs a big cleaning.
I would appreciate any thoughts/ideas on these. Prices were about $45-$75, and $145 for a Pfaff 135 that looked mint except the cord needs to be replaced. Advice?
The 15-88 is a treadle, 15-89 a handcrank, 15-90 electric with separate motor and 15-91 electric with potted motor. They are all the same machine; they just have different methods of power. The 15- or 15K is basically the same machine without reverse. The 115 is a rotary shuttle machine. There are many small variations, but any class 15 machine is worth having. If I could have only one, it would probably be a class 15 machine.
