One more bit of advice about these machines. They'll often have a noisy whine from the motor. This is caused by 60yr. old dried grease in the upper motor bearing. There are two fixes for this. One is to replace that bearing. The second fix, easier and costs less, is to put a drop of 30wt. motor oil into the top of the bearing and run the machine for a few minutes giving the oil time to soften the dried grease. I guarantee this works.
