This is so very sad. Clays guides were a huge help to me years ago. He tried to share his massive knowlege and others printed it and sold it for a profit leaving Clay in the dust. Clay deserves HUGE kudos and is a true unsung hero of pinball. I totally respect Clays views but his material should have been copywrighted so Clay would have received proper credit for his work. If that was done any profits would have gone to Clay or any charity of his choosing. Total respect to Clay for trying to share his amazing knowlege and doing the right thing. Sad that world we live in if full of sharks who will exploit a true visonary for short term profit. If nothing else I hope someday Clay will see that I posted "Thank you Clay!!! I appreciate your work and what you did for pinball"!!!

That is my recollection as well. I was told a certain parts seller was printing Clays guides and selling them and that was why the guides were pulled. I do not personally know Clay so my information (like most) is second hand. At this point the Bally and WPC guides don't need updating. Hopefully someday they can be printed and sold for the benefit of the next generation of pinball enthusiasts.
