Agood friend of mine sold chain saws from 1952 until 1985. He also repaired saws of all types .HIS thoughts of the wright saw was that if you like to be shook to death this was the saw for you. It could not be considered a serious contener to most chain saws. It was slow cutting and most people who bought these saws from him used them for cutting ice in the winter.They work great for that. He also remembered that when parts became hard to get people scrambled to get cutter bars. There were to two different styles of bars.
