Shopsmith 10ER Belt Speed Changer Control Magna 131-2 + Instructions + Chart
Some minor wear on the grey paint.
The listing includes the items in the last picture.
The knob can be used to fasten the speed change to the head.
The envelope is unopened but I believe that is a circular
cheat sheet to figure out what speed various Shopsmith activities should
be done at.
Found the original instructions. They will be included.
Shipping is $20.00
