There's Ross's machine...the EXACT model White-Westinghouse I played with in Tucson--YAY!! What year would this machine be? I'm thinking 1976-77 or thereabouts.
One thing I noticed that was interesting is that this machine has a 16 minute maximum wash time, whereas Roger's pre-WCI Westinghouse is 13. The timer diagram is a little different; on the Westinghouse it says "First Rinse" where the LONG spray rinse is, and on the White-Westinghouse it says "Begin Rinses". Other than that the two machines are identical.
