This is a vintage Revere Ware copper bottom stainless steel saucepan, 4-1/2 inches deep by 7-1/4 inches diameter. It holds 3 quarts to the rim. The stainless steel finish is shiny and clean with only minor fine surface marks from cleaning, use, and storage. There's a little fading to the black phenolic black handle and lid knob but they're sturdy and intact. The copper bottom was recently polished and gleams nicely. This is heavy Mid Century USA made Revere cookware. The Process patent mark with the Riverside Cal. designation was in use from 1949 until 1962.
