This is the 1952 Training Manual for General Motors Diesel Locomotives,  from the Electro-Motive Division. Printed in USA, spiral bound, measures about 5" by 8", and has 69 pages, plus blank pages in the back for notes. This book was used, so it is dirty from laying about, and shows some slight fingerprints. There is a name written on the top of the front cover. The pages are not torn or ripped. They are yellowed from age somewhat,  but are a clean bright read. Please ask any specific  questions after you look at the pictures. Thanks
