Technically, Ruckman didn't write the article, Herb Evans (Ruckman's friend) did, on behalf of himself, Ruckman, Riplinger and others. Ruckman put the article in his newsletter.

But to answer your question, I have the Sept and Nov newsletters (containing parts 2 and 3), but not the August newsletter (containing part 1). However, I recently obtained the entire article (all three parts) in text form from another source.
