70s vintage Sunbeam party percolator, 30 cup pot stainless coffee maker AP50-A

Vintage Sunbeam 'party perk', a 30 cup stainless steel coffee percolator in very good clean condition. (I don't believe this was ever used, though the original paper tag is a little worn, and dated 1972 in pencil.)  It's a Sunbeam model AP50 or AP50A, I think?
