"Expert" Diamond Jubilee?

Hi, everyone!  The version of Gregg that I learned was the DJS, but I always have had a fascination with what came before it and how the system was changed over the years.  Some of the elements of the earlier versions make sense, and aren't hard to read. 
DJS was easier to learn than Simplified, but it has its limitations.  Somewhere, I read that there was some book published called "DJS Expert" or something of the sort, especially for people who had learned the Diamond-Jubilee system, but who wanted to go back and learn more shortening devices for higher speeds.  Does anyone know anything about this?
