Warran and Ted Superior were not brothers in the saw manufacturing business.
Warranted Superior medallions are found on secondary lines manufactured by Disston and other major saw makers with other brand names on the etch. Some smaller 19th century saw makers may have bought sawnuts and medallions from the bigger factories.
After 1900 or so the "small guys" were actually secondary lines of the "big guys." The small companies were bought up by bigger ones and some of their products were continued for a time. Harvey Peace is one example. Most American saws from the 20th century, regardless of brand name, were made in the works of Disston, Atkins, Bishop, or Simonds.
In the case of Disston, their replacement medallions were stamped Warranted Superior rather than "Disston." I would speculate their rationale was they didn't want their name on lesser-quality saws. Brand identity and loyalty in the U.S. was much stronger in the first half of the 20th century than it is today.
