Old Specialised Australian Album

I have acquired the above. It appears to have been assembled by someone with very specific and specialised interest in early 20th century Australian one penny stamps (there seem to be but a few of other values). It contains minute pencilled annotations and also a pencil drawn schematic of these stamps' details with typed descriptions - which are meaningless to me as a non-collector.
Obviously (!) I'm interested to know if this collection has any significant value. Here are a few quick snaps. I can post good quality photographs if required with the obvious limitation of 200K resolution.
Thanks, Roy.

Fairly common fare, in the Australian discipline.
Referred to, generally, as a "study" of the King George V, "sideface" stamps
One of the world's challenging philatelic studies.

To appraise the value needs an expert,
One of our members "Aussie Al" I'd suggest, would be up for the challenge perhaps.

This thread will help explain those notes.

Thanks for the advice. I'll be posting some snaps of the annotation pages on the Oz forum to minimise duplication. My fault for starting two threads.
