Anyone now of a book detailing the history of combines and different styles? I'm a nut for older ones ( before 1990) but only being 29 years old have never really been around them. I have a brochure from JD celebrating the 50th anniversary of the cotton picker and it details all the models and advancements with plenty of pics. I would like to find the same thing for combines. Preferbly would include many brands. Does anyone know if a book exists and where I may find it?
