Michael Bowling article on early Crabbet breeding in Australia

I have read and re-read this article by Michael Bowling time and again.. and always learn something new. The article is about the early stages of Arabian horse breeding in Australia, and focuses on early Crabbet bloodlines. I am always struck by this photo of the magnificent Rafyk (by Azrek x Rose of Sharon by Hadban), a small stallion of 14 3/4 hands that looks like a 16 hands horse. Wow, what a horse! Why the heck were the Blunts parting with horses like this one?
