RE: sour cherry rolls
They were "Regal Crowne" sours, and they were originally imported from England. They re-appeared a few years ago, but as posted above, both Hometown Favorites, and one or two other "old time candy" sites no longer list them.
They had sour cherry, lemon, grape, and other flavors available, but the cherry seems to be what most people remember. I also believe there was an assorted roll.
These were one of my favorites, along with Adams sour gum (LOVED the orange!), which unfortunately has also disappeared.
