Whitaker Manufacturing Co.

Whitaker Manufacturing Co. made hardware and agricultural specialties, including files, in Chicago, IL. They were in business from 1903 to at least 1974. The address in 1914 was 509 W. Monroe St., Chicago, and by 1917 it was 409-15 S. Green St., Chicago. Their files were branded Triple Diamond or Whitaker. One source from 1914 gives other brand names, but these may have been made by another company. In 1941, the factory was in Clearing, IL (now part of Chicago). Thank you to reader Gary S. for his assistance.
