Shown is a vintage Sangamo Type-HC watthour meter rated at 115 / 230 volt, 200 ampere. It was in an old wooden box and I'm assuming it had been used as a test meter. In very good shape and operates nicely. I'm going to restore the test box and then reinstall the meter with new wiring as the old wiring was brittle and falling apart. I just love old things like this.
