Sounds like the Ray Miller books for the Ford Falcon and the like. I just hope, based on the title that it isn't a Mustang II book with Pinto footnotes.
Interesting side note. In 1993 a man named Norman Miller wrote a book on the Sunbeam Tiger. He aptly titled it, "The Book of Norman." He had 1,000 copies made and struggled to sell them at $50 each. Eventually they all sold out and and when he went back to the publisher to get more..., he found that they were out of business..., and the printing plates had been destroyed!
All of a sudden the book started climbing in price. Today roughly one or two come on sale in a given year. The average selling price is $1,500 and in one Ebay battle a copy sold for $3,455. While it has many 'never before seen' aspects - about two thirds of the book is an outdated registry. Many of you may ask why there aren't digital copies made. I don't know? Mr. Miller has declined to do so. Perhaps the unexpected notoriety is something he doesn't want to lose.
And, yes, I do own a copy. I won mine on Ebay in the very last second for $310 beating out a man who eventual became President of the California Sunbeam Tiger Associate. It is actually from a group of about 12 printer error copies where Mr. Miller (who BTW, signed my copy) allowed supplemental pages to be copied.
