Good Morning,
          Thanks for writing. I am interested in the manuals you may have. Do you want to sell it or can you make a copy? I am willing to pay you for your time if you want to print it off and send it out. I have been going over the harrow to make various repairs so still have it on the trailer where it is a t a convenient work height.  Actually, it is in very good shape but there are the usual consequences of age.... loose bolts, a broken weld, one bearing gone bad, and a pin or 2 missing.... all easy to fix. Everything is straight so I would say it was well cared for.
   Let me know what you would like to do with the manual.
Thanks,
           Cal
