    Trying to find the years and location of Sangamo in southern Illinois close to Herrin or Carterville. My mom and dad both worked there around the really 50s

    Thank you for this web site. I have a Sangamo DC watthour meter, S/N 295709, Model D-5, rated 50 Amperes, 125 Volts DC, Watthour per disk rev. 3-1/3. Seek to determine YEAR OF MANUFACTURE. I purchased it from an antique dealer in 1964 at a store in German Village District, City of Columbus, Ohio. It was represented to me to have been used to charge a doctor’s electric car in the early 1900’s in the same German Village District of Columbus, Ohio. Any information would be appreciated. Thank You.
