Help needed to identify these back covers

[Ameri]

Hi guys, I need the experts to chime in. Can anyone identify the books that belong to these back covers? I'm doing this for a friend and he provided this note: "The top of the first pic shows the back and front of all of the Red Ryder covers that I have. The encyclopedia is on the back of the Torpedo cover." Thanks!

I researched some. They appear to be all from the July/Aug/Sept 1941 period. Green Hornet 6, Catman 3, and Captain Fearless 1 have the same ad as the pink text "Three Great Action Picture Magazines" ad (not sure about interior back cover though). The "Bike Tires Built Like Planes" and "Take a Trip Torpedo" ads are from August and September 1941 DC books like Action 39, Action 40, Detective Comics 54, Detective Comics 55, More Fun 70, More Fun 71, Adventure 65, Adventure 66. Can't pinpoint the Red Ryder ad yet.

War Comics early Dell's had a back cover close to the one you are showing
