They probably haven't taken Down yet
John, the ebay seller in the link, and I co-own a bunch of books we located in a collection a few months back. So, at the show a collector with the SS 7 approached John about trading for one of the books he and I co-own. Since I was at the show, we were able to make the trade for the SS 7. I've contemplated buying John out of his share of the book and keeping it, but he wanted to test the waters with it first. So, there you have it.
Thanks Bill... my curiosity got the better of me. Thats a helluva book!
