I know that.
My point is why is Bomford’s the only Australian cert that makes reference to a Book and Page? None of the others do.
Check out the this thread and look at some other Australian certs:

None of the Australian samples reference a book or page.
Book and Page are key. on Ancestry.com, they do have book and page for the HIN district in South Australia. It would be fairly easy, I suspect, to determine whether or not Bomford is at Book 44B Page 5733.
