This is a simply stunning Art Deco-design coffee percolator. It makes up to 10 cups of coffee. Plug it in and it starts percolating. When I tested it with just water (no coffee grounds) it got right to work and took about 9 minutes for brewing. The light did not come on when completed, but flickered when I moved the knob from milder to stronger.

This is used and does have some inside coffee staining/residue and a few marks on the outside, see photos. Overall, it is in very good condition for its age.
