This high demand two-volume set published by John & Carol McDougald is now out of print. The original owner removed the comb binding and punched both volumes so they could be combined as one in a large ring binder. Both volumes are complete and in excellent condition (first page signed by authors and owners). For additional information you can go to: http://www.insulatoremporium.com/books/insulhistory.cfm

$40 ppd Media Mail in the US (additional to Canada)

I also have many past full year sets of Crown Jewels of the Wire. Contact me with your needs. Excellent volume discounts available.
