Nice
Wow, that machine is absolutely beautiful! The racks, sink and top (is it stainless or Monel Metal?) look factory new. I'm used to seeing them in white enamel, which obviously doesn't usually hold up over time as well as this. It looks to have been very well taken care of. That was an excellent idea to put new works in to keep it going.
I imagine this was a very expensive piece of equipment in its day. My dad's aunt and uncle's house, built in 1936, had cabinets and top very similar to yours, but no dishwasher (why, I don't know - they could easily afford it) though it had a big double sink. When we sold their house in 1991 after his death, the sinks and top looked almost new. They were Monel Metal by Whitehead Metal Products. I remember the sink drains were oversized, and their new disposer had to have a reducer ring like yours. I think only large commercial disposers use that large size opening now. Anyway, you have something very unique and highly prized.
