Revere Ware produced these in three different capacities initially, 4, 6, and 8 cup. From a 1955 catalog:
Later they seem to have added the 10 cup “party” sized percolator. From a 1966 catalog:
Use 2 level tablespoons of regular grind coffee to 1 measuring cup of water (cold). Place on medium flame, keep on flame for three to four minutes after percolator begins percolating. Then take from burner and remove basket and coffee is ready to serve.
Additionally, here is a pretty good general guide on how to use a stove top percolator.
The most common problems with these percolators are broken glass lid knobs and worn bakelite handles. Replacement handles are not available as far as we know.
For the glass knob, luckily, Fitz-All makes a universal percolator glass knob that works fine for the Revere Ware percolators. It has two pieces, the glass part above the lid and a “nut” below the lid, so it clamps on, rather than screwing in like the original knobs did; but it works great. You can find it here. Update: unfortunately the manufacturer of the replacement percolator top changed their design and the metal ring is now slightly smaller, and just a bit too small for the Revere Ware percolators. 🙁
