Purchased this Rockwell 46-525 lathe off Craig's List. Drove to Wilmington, Delaware to pick it up. Ad said the motor didn't run. The price was right. It had the tail stock, tool rests/banjo and other accessories so I thought I would take a chance. My thought... have the motor checked out and in the worst case I would need to purchase a new motor.

There are several good web sites out there for those wanting to research old machinery.
You can still get parts.
Here are some images of old Rockwell lathes.
