FoMoCo updated them every year until the war. They are out there. In 1939 when the Mercury came out, they started splitting the years away. I have one that was for 1938 to 1941 that includes trucks & Mercury cars. They always had a master parts book for the Ford cars though. The November 1950 revision was the last one for the earlier years back to 1928. Every time it was updated, replacement part numbers won out over original part numbers that were superseded by newer parts.
