It has been posted on here before and I have been told at a show that they will offer 2-5 dollars a kit if they are the normal kits. they get fast sellers along with slow sellers. That is why the price is so cheap.
Some pictures to look at also. https://www.bing.com/images/search?q=1930+model+aa+ford+dump+truck&qpvt=1930+Model+AA+Ford+dump+truck&qpvt=1930+Model+AA+Ford+dump+truck&qpvt=1930+Model+AA+Ford+dump+truck&FORM=IGRE
Are you asking about The Directory? I will say that when I opened the front cover(to find an email address) it has a reference to a Revell reference book, Remembering Revell Model Kits and Monogram Models. First I have read the front of the book.
