These regularly published books have become a dealers Bible, as the dealer collector friends I know use them religiously!
I used to buy these as they were very good reference works, listing quite a lot of the versions of the models we collect here on the forum, but in later issues those versions are not recorded, somebody pointing out the mammoth task to keep adding and updating the book to include further versions and variations.
One edition even included Scalextric models, but that has been dropped from further editions!
These are interesting to see what the Author and the contributors think certain models are worth, but use it only as the title implies...a GUIDE!
