I'm also looking for that book. Called the company, they said his wife might have a few copies but not going to print any more when they're gone....lee
RH Machine the hard chrome tool maker in Idaho has copies of the book for sale. Ray Stueckle was one of the guys that started RH if I remembor correctly.
I have a copy of Ray's book here somewhere, just not sure where. I read the section on the Massys, but just remember it not being very helpful, adjusted the air deflectors, or maybe just took them out, been a long time since I read it. If I can find it, I will let you know.
I know loewen used to sell them - you could try them to see if they have any left. There was the conventional book, and the rotory book. I believe there was also a 3rd book full of testimonies.
