I picked this up this morning its in OK shape the dude was not careful removing it as you can see from the bottom left corner he also destroyed the bottom cover It need a few parts and I haven't hooked it up yet for a test run. I'm sure I will have some more question for yall later ( this is my first vintage DW) but for now here are some interior shots
I would not have pegged that for a Roto-Rack. Congratulations, it's a beaut! Those D&M bottom panels are pretty interchangeable, so it's more a matter of finding an avocado one for you.
Yu can barely see the tip of it in reply #3 photo. And I'm like you Nate, I would have never pegged this as a roto rack. I had it down as the first version of the rectangular upper rack.
