Richard, the photo I posted is a 1990 model. Variable speed DC motor, reverse tumbling, slower ramp up to spin, electric drain pump, etc.
If the one Chad posted at the Re-Use Center is an early '70's model, it will be a 3 belt design, solenoid to engage spin, faster ramp up to spin, etc.
A really neat machine and I agree completely, GO get it if it's still there!!!
