Malcolm---I used to have a 1959 Lady Kenmore set. The washer had never been used. In a fit of utter stupidity, I sold the pair after a year to a nice, young Hispanic couple who needed a good washer and dryer. This was before I found AW.
Still kicking myself once in a while over the decision to sell.
In answer to your question: the lever on the right side of the console controls the automatic fabric softener dispenser. The reservoir is located inside the console (the top pops off the console). It will dispense 2 to 4 ounces of fabric softener at the start of the rinse cycle. Or you can shut if off.
