This is a "copy" of a  Wheel Horse "Instruction Manual and Parts List for the RJ-58 Tractors.   This Manual measures approximately 7 1/4" x 5 1/2".  This was copied from the Original.  I sold the Original on Market place 3 weeks ago.  A little research said it might have been a Salesman Sample.  Any bodies guess.  Thanks for looking.  I also have other Wheel Horse Manuals.  Reprinted on a Laser Printer, not a cheap copy machine.  You decide if this is what you want.  Buyer will also receive 2 FREE Wheel Horse Decals as pictured.
