Welcome to the club. I think that B. W. Schulz was a friend of Richard Rawe's, but since Richard's death it has been difficult to reach him for comments.
It certainly seems that B. W. Schulz is interested in being an unknown, and I can understand that. no one wants to become "Exhibit A" in the museum of how much the WTB&TS can mess with individuals. The Watchtower has financial resources far greater than most of us.
My take on it is that B. W. Schulz is a pretty fair chronicaller/historian and offers material not found elsewhere.
"Timothy White" was another reclusive historian. I was able to "crack the code" on Tim. Perhaps you'll be able to do the same with B.W.
