If you're interested in how gauge blocks fit into the history of precision engineering, a new book called "The Perfectionists: How Precision Engineers Created the Modern World" puts them into context, and presents a very interesting perspective on the events and developments that brought us into modernity. These blocks feature strongly into the industrial revolution. I strongly recommend the book! https://books.google.com/books?isbn=0062652575 https://books.google.com/books?isbn=0062652575
