The first time I saw one of these I thought it was a percolator missing the basket, but they did in fact sell these as a separate product. This is exactly the same as the bottom part and the lid of the drip coffee maker.
Replacement parts
Really the only thing to wear out on the server is the Bakelite. The lid knob is standard Revere Ware just like the ones that we sell. The handle is not available from anywhere.
