A booklet written by the Riehle Co. describing "The Largest Universal Testing Machine in the World" which they created to build the Hudson River Bridge ( now the Geortge Washington).
Heritage Auction was unable to give me any information about this booklet. Another dealer suggested I donate it to the Smithsonian because he thinks the machine is there.
The only other copy I could find is at the webstie below.

I would appreciate any information regarding it's value and a market for this type of publication.
Thank you so much.
