Not sure if this machine is old enough to talk about in this section -
I retrieved it from my daughter last week. She hadn't used it in over ten years (I did leave a Singer 237 for her to have SOMETHING to sew on)
It still runs like a champ. I darned socks with it (yes, there are people that actually still do that!) and darned the holes where the buttons pulled off a couple of pockets.
I am still in love with that Bernina 530-2 from 1962!
Can't figure out how to oil the spots it should be on top - the instruction book - such as it is - shows where it should be oiled - but doesn't say how to get the 'lid' off.
