I have that exact twin tub, Bought it from a guy who was selling a pink 652 and a 960. He then told me about it so I bought it aswell. They all came from his mom and had spent their entire lives in a sleepy town of Fish Hoek here in Cape Town.
I used the twin tub a few times until the pump housing started leaking badly. A few weeks after this happened [about 2 years after I bought it] I cleared out a old vacuum/ appliance shop store room and low and behold a brand new pump housing and belts and a few other bits were found in the spares we bought also included were the rubber mounts for the motor. Its amazing how well these old washers work
