Wow Phil, these are amazing finds indeed!! In the parts list for my Inglis Sterling, they show two versions of the timer box - one for the Sterling and one for the Superb, so other than the Suds-Saver, the machines look to be the same! If you do wind up needing a new pump, though, let me know... I have a *few* spares now... LOL
Now, that dishwasher really threw me for a loop - I also was scratching my head at the GE stainless bowtie impeller with D&M upper racks. John, thanks for the background information on that one - the only vintage Inglis dishwasher I got close to was a 1967 front-load convertible model and it was 'pure Whirlpool' inside.
Dang, I have to get up to Joliette again soon to see these up close!!!
