Those pictures look like they could have been taken in Roger's back yard, but then most of Tucson tends to look the same to me, and I also think I'd have seen this machine on past visits. Roger doesn't own a dog either.
The machine looks nice, but the price is kind of steep even though they're fairly rare.
This machine was made in three sizes; 6, 10 or 12 place settings, I think, and this looks like the large one. This finished the rinsing by fogging the load with steam which, as it condensed, gave the equivalent of a distilled water rinse.
