One thing's for certain, at one point it was glowing.
I often....."acquire" old buss bars for radio grounding, I'm not sure I want these.

Glowing indeed! Notice that the failure point appears to be where the busbars were joined?
Stupid should be painful.

I have never worked with busses like, how are those bars joined? could a bad/loose connection have aggravated the problem?

Wow, I wonder if an infrared camera would have picked up the problem, before it got to that stage? We do infrared 2x year.
