I had a Fanner 50, but my shootin' shell rig was a smaller revolver, Peacemaker style; it had a leather belt and holster which seemed good, realistic quality at the time. I also remember the snub nosed detective revolver. That also came in a "detective's kit" with a Thompson!
Roll of caps here:

Adults would come from nowhere to see what was going on.
