I have a nice copy, at least as of a few years ago you can get them for relatively cheap. I've been meaning to put scans of the text into OpenCV and play a bit to see if there's an underlying code. The number system in the page numbers has been cracked as far as I know.
It is so strange that books like this cost hundreds and hundreds of dollars to buy.
You might think the publisher would ........ publish some to sell.
Copies hung around my partners secondhand bookshop for years. This was in the 1980s. Properly shelved under "esoterica"
1st Ed. Now worth $6,000 oh well.
