I can't get at my copy just now, but if you have the Action Comics Archives you can look up the issue more easily. I have too much stuff in the way, so I can't get at the book. instead of "pages" missing, it sounds like actual paper is missing, so not page 2 & 4, but leaves which would be story pages 3 & 4 and story pages 7 & 8, maybe? I can't get your pictures to load, so I don't know what it looks like. "page 4" could also be a pure advertising page, so it was torn out and no story is missing. there's too much to speculate about this.
