From the Foreward to the book: 

"This work represents a large and valuable group of practical sheet metal pattern layout problems, presented in a clear and simple language.  It is intended as a complete shop guide showing a step by step solution of several hundred sheet metal problems met with in day to day practice by the average sheet metal worker and layout man."

This gem is aged for sure, but that just gives it character! Very cool old book!
