All hail the Mighty AM-9-T2! This one looks nearly new. Must be low mileage and only used with soft water. Interesting booster heater as well. I have used this model and it will damn near outlast and outwash anything. Weird hood system though. Looks like the vents that would be connected to a conveyor unit just hung next to a door machine.
