Nice original 1951 SAFETY RULES book for the BALTIMORE & OHIO RAILROAD COMPANY and a 1953 B&O Time Book. The Rule book is in excellent condition and appears to have had little use. Only writing in it is the name of the original owner on the inside cover. Binding is nice and tight. One minor crease in the middle on the binding side. The time book is in nice condition with the employees' name on the front cover and some neatly detailed time records from 1959. Please see photos for more details and to evaluate condition for yourself
