I found something to do it is a giant binder of i&t tractor repair manuals! And along with it was a couple of these red books from the 60s way before my time! And in the red book was the ad for this big binder of 58 manuals and a binder of flat rate repair books on different models! So apparently this all came in a set! Would be worth alot if you had to go buy new reprints today thier about 20 dollars a piece I have paid! Now were did I find this set well I work at a garbage company and someone cleaned out a house and just happened that the only guy (me) at my company that is into tractors found it guess I was ment to have somebodys repair books! Funny how things happen!
