The family I bought mine from said that the mother bought it new in 1962 and used it until she moved into assisted living in 2001. It came with all the original tags and literature.
What is interesting is the ability to start with 20 gallons of hot water, running whites and bedsheets, then the same hot water for dress shirts, then dark slacks and black socks, then dark tee shirts, then the last load of heavily soiled denim workclothes. 5 loads on one full tub of hot water and 2 rinse tubs of cold. That’s undoubtedly more “water efficient” than the “makes your laundry smell like mold” save the planet HE front-loaders...
One day I will find the girl of my dreams... one that that gets as excited as I do about laundry day. I mean, no more going down to the crick and beating my clothes on a rock... I have upgraded to all the modern conveniences... All made with the modern housewife in mind!
One day.
It’s good to have a dream...LOL!!
Since ours was gone by the time I was old enough to be tasked with doing the laundry, I wasn’t aware of those water-saving attributes you mentioned.
