       Solo 640 (Early) Information
       By: Hoggwood Date: August 9, 2016, 2:00 pm
       ---------------------------------------------------------
       I am wondering if anyone has any documentation on this old saw.
       IPL, owner's manual etc. for a late 60's early 70's Solo 640.  I
       picked one up and it has some interesting features and design.
       Thanks for any help.
       Cory
