Mate, I would love to be able to help you out there but unfortunately the book is some 75 pages long and some of the illistrations are triple page, as you can see, it rather well worn and is over 100 years old and it is one of my favourites
.
Being keen on refractors myself, it sits in an area that has pride of place.
If you are ever near Cootamundra, your more than welcome to call in and have a drool, sorry, meant look at it.
Cheers
John G
