If it's all original and in good condition you should be fine. Give it a good inspection. Are the cords flexible and not brittle? Is there any exposed copper on the wires? Are there any signs of overheating(dark burnt looking areas, etc)? Are there any splices in the wires or any signs of a prior owner messing with the wiring? If it checks out ok and everything works you're most likely fine. Most likely is just because I can't see the machine myself.
Pictures of the machine are always welcome.
