Electric primed 5.56 mm Folded


#1

Does anyone have pictures of the electric primed 5.56 mm folded cartridge that was tested in a converted Thompson/Center pistol and maybe also a M16 rifle? I’m aware of the electric circuit test cartridge with the light diode but I wonder if loaded cartridges are known by collectors.

Edit: The converted pistol tested was reported as a T/C but in fact it is a Sterling single shot.
