I watched the video of the Gibson Ortho 77 Uni-Race, and I'd like to know more about the history of Gibson and whatever their fate was. I searched Gibson in the gallery, but I didn't come up with much.

If you're talking fluorescent fixtures, I've heard of preheat 4-lamp halfpipers made by them, and I have a pair of "Metalux Corp/Gibson Lighting Inc" mid-late 70s era surface-mount 1X4 troffers from my school.  They also have era-appropriate, possibly-original Advance Kool-Koil and Universal Therm-O-Matic ballasts.
