MarcTed,
I don't post much but read the board every day. I always especially enjoy your thoughtful and thought provoking research and posts. Regarding back designs, I have always felt that the Piedmont and Tolstoi backs were identical as well. I don't know what, if anything, that adds to this discussion but I think it's interesting to note. I have also noticed the ABCD similarities and feel that your explanation makes a lot of sense. Keep up the great work!
