I know exactly how a 201, can get into this sort of state, because its roughly the state my latest girl was in.
Our elderly friend was downsizing, and my husband was helping him clear out his garage. Trapped in there, amongst cartons of books and stuff, that they hadn't unpacked in over a decade before, was this cabinet. Our friend had forgotten it was there .... a 201, converted to electric, in an unsealed shed, covered in possum shit and grime. It belonged to his late wife, her mother's machine. Bought from new, converted in the 60's or so, banished to the shed when a new one came along. I said no at first. She was filthy, and my love affair is mostly with manual machines. He tried listing it, but no bites. So he practically begged hubby to take it, not wanting to take it to the dump shop. When it arrived I refused to bring it indoors it was so dirty. I took three buckets of hot water and sugar soap to clean the cabinet. And then two coats of beeswax (it needs more). The machine is serviced now, but its tucked away for now, trapped behind the extra couch that my daughter bought, waiting until she moves out of home.
These machines come to us, because they know we will love them. Simple.
