Surfing on the Internet for my own research about the history of shorthand I found such a book:
It looks just like Gregg's, but strokes/curves are matched to another consonants. But the rules, as just discussed circle rotation, look the same.
It was first published at 1885. So, it looks like J. R. Gregg was not the revolutionist, but evolutionist - in the great Open Source World of Shorthand - and finally won in the competition.
