I've noticed that there are many people looking for Handles, Lid Knobs, Pressure Cooker Lid Gaskets and hardware (threaded rivets and screws)for the older pieces of Copper Clad Revere Ware. Revere doesn't offer spare parts like these (they stopped back in 1989) but I finally found a place that will !!
This place has bakelite handle parts and hardware (even Pressure Cooker Gaskets) to fit old Revere Ware.
They have a great collector's web site if you need information or product history also!
