The big Canadian manual was based on a wartime technical manual and is the best available for the old Fords. I've had one for some time. They have info about just about everything in there. The reprints are pretty good but originals are always better. If CDs are scanned from good copies then they would be less expensive.
The one I have is the 1939 through 1948. It has the US section I first and the Canadian section II second. Most are green colored and are service manuals for Ford and Mercury US and Ford, Monarch, and Mercury in Canada for both passenger cars and trucks. There is also one for 1932 through 1938.
