That's the stove that caused bad feelings, for a while, between BS&R and Martin Stove. BS&R had a stove called the Big Boy that sold well. Martin later came out with the exact same stove, called it the Fatso, but it was 5 cents cheaper. BS&R's loyal customers all went with the cheaper Martin Stove. Mr. Jones, of BS&R, called up Mr. Martin, mad as hell. He was mad that Martin had stole BS&R's design, but was also mad that Martin sold theirs for less. According to the story Mr Martin told Mr. Jones that Martin had to sell the Fatso for less then BS&R's Big Boy because it was a 1/4" smaller!! Martin had gone out bought a BS&R Big Boy Stove and took it apart and used the parts as a master pattern for the Fatso.
As ole Paul Harvey used to say, now you know the rest of the story.
