The Factory Photos CD was published by Clive Law
https://servicepub.com/clive-law as part of his Service Publications project. It was a collection of the original Ford and GM photos taken at the factory (possibly with some DND photos) of most CMP models. The emphasis was on cab and chassis, as you might expect from the auto companies.
I just checked on line and don't see a listing for the Factory Photos CD on the listing for the folks who have taken over since Clive's death.
https://servicepub.com/publications They do list Clive's Drive to Victory as still being available
https://servicepub.com/product/drive...tskin-vehicles along with many of the books/booklets published by Clive. No harm in sending them an email to ask if the CD is still available.
