Washington Government Printing Office printed this Rules & Instruction soft covered book. The title on this book is "Interstate Commerce Commission Division of Locomotive Inspection – Laws, Rules and Instructions for inspection and testing of Locomotives and Tenders and their appurtenances." This book was carried around and used over and over. Great illustrations, tables and laws for the train connoisseur to peruse. A wonderful piece for the collector of train memorabilia. The book can be read but it has been used and you can tell by the pictures.
