Thanks for all your comments on this, Folks. Here is the bottom line.
Regarding the Verichrome, it was, in fact, not exposed. I didn't find this out until after I loaded the film on the reel. When I started to peel the paper off in the dark, I thought that if I felt tape, and not film, like 120 film, the roll would not be exposed. I felt film. So I loaded the roll. No tape on the other end either; must be a characteristic of 127 film. But after the film was in the can, I looked at the paper. Sure enough, on the spool, the gummed paper tab said "Exposed". That would have been on the outside had the reel spool been through a camera. At least I saved the development time and chemistry.
And regarding the big roll, it was a 116 or 616 roll, bigger than 120 film. Somebody on this thread pointed me to the Rescued Film Project. I noticed some big film in one of their videos. I reached out to him/them, then he/they pointed me to a video showing how to load that onto Paterson reels. It wasn't easy, but I got it. Unfortunately, there was nothing on the film. Eight minutes in HC110 dilution B with an ounce of benzotriazole. Completely clear. Better luck next time!
