I just recently picked this rare CES, California Electric Steel anvil in near pristine condition. It was manufactured in Angles Camp California which happens to be only a couple hours north of me. The gentleman I bought this from purchased it new from CES before 2000. Anvils in America lists this anvil on page 512. They only show that they made one size of anvil called the Model 200. Specs are as follows: Weight: 188 pounds. Material: 4135 Steel. Heat Treated to Rockwell 42-45c. They sold new back in 1997 for $551.25. As far as I can tell the foundry is still in operation but not making anvils
