Vintage CHAMPION Saw Jointer. Has Pat. - May 5, 1874; June 1876; Aug 1881; jan 1888. I believe this is a logging saw tooth leveling jointer tool. It's in good vintage condition. There are no other manufacturing marks that I can see. I believe all the screws are original to the tool. What a great tool to add to a box of tools or for display. View photos for best description.
