Here's the deal. The Brooks Pat insulator plus a hard bound copy of Stephan Ambrose's "Nothing Like It In The World"; the story of the building of the transcontinental railroad. Amazon rates the book as 4.6 out of 5 stars. Brent Burger thinks it sucks! Some great photos. This insulator may even be in one of them. I'm asking $173.00 plus actual shipping cost. PayPal (friend mode) or check. Any questions? 860-970-7305 most any time.
