Here's a great antique Mack model A51S parts book from 1951. These are very rare it may be a long time until I see another one. The info and diagrams are worth a lot to the collector and lost to time. You could even copy a lot of the diagrams and frame them to resell. This is part of a large collection spanning 40 years I will be listing each one individually. Look back for new volumes. .
