maine 54,
I have an original 1954 Chevrolet Truck Data Book that is dated June 22, 1953 (for all pages except for the Index and Color Choices, they are January 1953) and the PRICE LIST (January 4, 1954). It has the '54 Sedan Delivery in the Vocational vehicles section.
Not only is Keith correct about different issues/editions, but it is also possible that sections of any given book might have been replaced during the year (the original Data Book has a metal, multi-ring binder that opens and closes).
