are you sure you didn't just repaint this thing too while you were up there? this thing is in better condition than some of the new siemens/eagle signals that go up around here. some are strting to chip (namely the ped signals, the traffic signals seem to keep their paint better)
It was recently re-painted. The main housing still looked good, but the backplate and visors were fading. The whole intersection's heads were re-painted.
The remaining CGE/Fortran signals and the Eagle Flatback signals installed in the 60s and 70s still have most of their paint on.
I believe McCain was the worst at keeping their paint.
Glad to see this classic light repainted though.
