This is an ORIGINAL Allis Chalmers "Corn Heads" Parts Manual (Form 9004760, April 1976 printing). NOT A CHEAP REPRODUCTION. This manual has super illustrations as well as having in-depth parts identification information for these classic AC combine heads (covers several models, please see pics). The cover is in good shape with light wear and soiling. The spline is tight and intact with NO loose or missing pages. The 110 pages are also in good shape. This manual is in GOOD overall condition.  FREE S & H. Thanks for viewing.............Triple K
