I have been away from the site for awhile, but getting ready to sell part of my collection. I noticed you WERE looking for a FS Jr. I am selling three , blue (model 15 blue dome plastic) and a red (model15A, glass dome) and a rare amber (15A, glass dome). A little late and not sure if this helps you. Plus, I have two chrome base rings and 2 red glass domes and one plastic red dome.
