Carl, keep an eye on the info from Bus.
I saw the one you were talkink about for 175, there is another for one ninety something.
I saw one sell recently for $75
in Nov. 2009 I sold a few duplicates that I picked up.
Shulz's $71
Larry Finch 1983 for $14.25
Shockley's wrench patents #1 $32.59
Shockley's wrench patents # 2 $32.59
the reason that I had duplicates is that I found Shockley's #3 but I had to take all five books,
after selling the 4 books, my #3 cost me nothing.
good luck on the one that Bus is listing.
