I have an original-looking single-volume manual in not very good condition that lists Chevrolet Trucks "1948 to 1951 Models with 1952 Supplement." Its copyright date is 1950 and on that page says reprinted with permission of General Motors. Go figure.

Just as a comparison I have the manuals for 1998 GMT 400 models through 3500 series that comes in four volumes and makes a stack about a foot high.
