I just downloaded the catalog and was looking trru the pages when a question arose.
Where does it state the year? On page 40 it has a listing of tappent wrench applications for cars. It only goes up to 1941. If it is a 1947 catalog it should have listings to 1947. Car manufacturers didn't change their engines after the war until 1948 and up, so a 1947 engine would be the same as a 1941.
I'm guessing it's a 1941 or 1942 catalog. Of course if I missed the print date, then I'm wrong. Anyone have any comments?
