Lot of 2 vintage engineering books.

Both were purchased at an estate sale of a former engineer working for Dupont.

"Cameron Hydraulic Data" book has the name JB, Del Papa written in blue pen on the first page.

"Compressed Air Data" book has the following written on front page: JB, Del Papa Kingston, NC. On inside of front cover. It has notes and formulas written in blue pen. Writing is very tidy. Please see photos to see these two areas. JB Del, Papa also wrote his name on inside of back cover.

Both books are in good, vintage condition. The Cameron Hydraulic Data book has a crease down center of front cover. Please see photos of books to help determine condition. They were well used.

These books will ship via USPS media mail from my smoke free and pet free home.
