Thanks for trying, but they were not listed. I’m surprised, because they were fairly common on the shelves, in gas stations, through the late 70’s. I lived in the Chicago area. This link below, shows the hard candy which the ingrediants seemed so similar to.
The ones I’m referring to, were wrapped in a light colored roll and had a wax paper inner liner. It was similar in size to "Rolo’s" or "Sweet Tarts"
