Interesting. There was one of these available on CL here locally last month. I had just picked up the KD-2P, so I passed on it. From the pics, it looks like the one I passed on was in no where near as good condition as yours, though.
Question: were all the KD-10's free-standing, or were some built-in?
A freestanding KD-10 would have worked well enough on my patio kitchen, since I decided on a more or less permanent location for it at the end of the countertop. Although plumbing the water inlet and drain lines would have been a challenge. The vintage sink has a wall mounted faucet with steel rigid supply lines, and no provision for a disposal or dishwasher on the drain.
