I dont have anything that old but I have a 1982 kenmore that i rely on and a 2000 singer thats fairly new I'm iffy on. My parts are on backorder so I can't work with her yet. If my kenmore crapped out I would be devastated
I have a 70's Necchi I took in repaired her she has several stitches but not computerized
she has switch under the plate that would get flipped seems to have worn for bobbin winding...
My knees I could not handle a treadle now bad enough best on white they are knee feeds
my greenhouse died this year told the other half build one in fall already had one garage dedicated this year
