When I first caught a glimps of this machine, I was CERTAIN that it was a Pulsamatic -- the knob and motor reset button placement was different, and the Ultra Clean script was different. I wasn't too disappointed to see that it wasn't a Pulsamatic; I was even wondering if maybe, just maybe, some of the last Pulsamatics spilled over into the 1959 product line. Steve Riley talked me back to reality, and either way, I am very happy to have found this machine.
The rust in the tub is very crusty. I really don't think it is surface only. If not, you all will see a begging post from me for a replacement.
