An invaluable resource for those interested in the history and development of porcelain insulator manufacturing in the US! Brent retired as president and chairman of the board at Lapp Insulators. This copy looks unread but has some wear to the jacket. I really enjoy this copy has 2 original tri-fold brochures about the book's release which include a number of reviews by industry leaders.

From a smoke free home. Let's go $14 shipped to the US!
