Mmmm. . . don't want to get caught up in one of Jacko's things so I'll fade.
Just want to say, the info I posted came from not only a couple of books (same story in each) but also a few conversations with blokes in the Canberra Assoc.
Finally, find myself in agreement with Jacko though. The fact of the three 9s is well known, and has been for at least 20 years, even though
detail may still be blurred. Can't see the need for secrecy now except, maybe, for political reasons.
