Looks like a 1964 or 1965. I used to have a 1961. Find out if they know if it worked or not and how long it's been sitting.
It's a condensing dryer and uses cold water while drying (about 30 gallons an hour). Great splashy wash, does a great job washing, but has no suspension and spins about 225 rpm. If you have any interest in W/D combos, I'd say grab it, especially of you can talk them down on the price.
