GB2 Semi Hero Bargraph
After exhaustive research and thanks to Ken Huegel’s pictures those few years ago, I’ve identified the semi hero bargraph.
Eaton Roto-Tellite
It is a static rectangular display light with 2 small flange bulbs inserted through the back. What they ended up doing was tearing apart the assembly leaving only the rotating indicator portion. It was installed in the gun body by attaching a piece of bent aluminum to the indicator and using a #6 button head bolt.
They were used in just about everything including the space program. The “stripe” pattern may have been original but likely printed and laid in the indicator.
Nothing flashy but they got the job done.
