I too am confused by this new volume, and this with TWO versions of the 7th Edition of the Bull ESC. Which now is ESC? And I am miffed by mistakingly getting the abbreviated 7th Edition as at the time of purchase did not know this.
Another issue is that in the proofs and patterns of the 20th C. predecimal series have been in many cases mucked up.....I know, I sound the crybaby.
