TITAN 4100.

History: The saw was purchased by Joseph Mirisciotti Sr of Canonsburg, PA in the late 1950's at a local hardware store in downtown Canonsburg, PA    It was only used 2 or 3 times that we are aware of and that was to cut a few trees at their hunting camp.  Joe Sr worked in a steel mill in Canonsburg and became disabled in 1962 when a load of steel beams fall from a crank and trapped him.  From that date he was not able to walk so we know that the saw goes back before 1962.  The steel mill made beams for bridge building. Joe's father Joe passed away 12 years ago and the saw just sat.  I got the idea to sell then I ran across you and Joe feels good about you having the saw.  I hope you are happy with it... Lee Nickovich, Joe and his sister's.(from MEADOWLANDS,PA) Bolens made a re-badge (copy) of this saw being sold as their model 3010 Thrifty.
