Honesty without fear?? How funny, you'd think they would have told customers about the reliability then. Although, this washer seems to have fared pretty well given it's age.
I had a later model Kelvi-WCI with a plastic tub that was OK, rollover wasn't great but with a long wash, it did the job. Can you snap a pic of the tub and agitator when you have a chance? That turquoise color is very cool.
WCI made a similarly designed machine for lots of brands, I've seen Kelvinator, Bradford, Coronado, etc. all with very similar styling. Never realized they were pull-stop/push-start though, that's very Kenmorish!
