I may get some better pages for this.
I offered a copy to a guy who is restoring a Hawker Australian Demon and his comment was "My interpretation is that RAAF used Hind data to manage Australian Demon, and that RAAF markups/ALs on Hind documents are invaluable for understanding the Aust Demon. "
He has another copy that may be to a different revision standard and I have asked him to send me a copy of the cover and the pages that are most unreadable in this one IF he has digital copies of those pages.
