That’s the same brochure I found. Not to much info about these on line. Story behind it was a family member bought a farm 40+ years ago and they recently found several implements in the woods long forgotten about. This plow was one of them.
Plan to try it out some before taking it apart to repack bearings. Everything turns smooth and quiet
Dearborn implement documentation is kind of terse. That manual is typical of what you will find.
The corporate history of Dearborn Implements is pretty well documented.
The Ford/N Series forum on Yesterdays Tractors or the Ntractor Club forum is the best place to ask specific questions about that plow or Dearborn implements in general. Many of the participants there have day one experience with them.
I have a ckassic setup here - 1950 Ford 8N with 2 bottom economy plow and 6' Type E disc harrow. Everything pretty original and complete.
