Thank you, Kyo for pointing me to Ben. I sent a quick email and Ben said:
"I know the book. Somewhere in the world I probably own a copy…. but i suspect its deep in a box in my mothers garage half way around the world…. From what i can recall the book covers not much more than a list and photos of pre90s coca-cola russell yoyos from Australia. you will probably see a broader assortment of yoyos on ebay in any given day but it is nice to know the range. As far as international stuff…. its vast. I still see new yoyos all the time pop up on ebay and i thought i had seen them all years ago….
but yes, someone should make a nice site, even user submitted would be cool!
It wasn’t a sweet PDF scan of the Aussie guide but the site is VERY cool, is more up to date than the guide, and might be of interest to other vintage yo-yo collectors.
