For sale is a vintage Hydraulics book/textbook from the Henry Ford Trade School. Copyright is 1941, Reprinted in 1947. This book is one of a series of lesson sheets prepared by instructors in the Ford Schools for the instruction of Hydraulics. Estate purchase. As you can see from the detailed photos, there is plenty of wear/discoloration on the front and back covers, and the area covering the spine of the book is coming off. However, all of the pages of the book are intact, and all look great other than having some of the discoloration you often see in vintage books, a stain/mark here or there, and some slightly curved edges. Please take a look at the photos for a good sampling of these issues.
