Then there IS hope! I took in a 500 in similar condition yesterday. I need to get photos today and get an idea of what is missing. Right off I know I am missing the face for the tension, the spool pins, the upper lid and the side lid needs work to stay on. The machine desperately needs cleaning and oiling but the motor was making a horrible growl when the poor woman tried to demonstrate it for me.
This one is going to need donors to live.
I will keep the motor oil tip in mind. This "screaming" sound...is it truly a higher pitched scream? or does growling qualify?
