Directory of American Toolmakers Information
Frank Chandler and Charles S. Farquhar, dealers of tools and supplies for all sorts of metal workers, added "Co." to their name in 1904. They made no tools themselves but it's unclear whether they re-marked any of their products.
Chandler & Farquhar still operates out of Randolph, MA.
