You read my mind Steve.
Is it a GE, cross bread, or other?
GE had a solid body light that closely resembled the ornamental eagle. But solid bodies are usually found in the mid/late 20's to early 30's.
Did Eagle ever make a solid door light?
There were some 60 traffic signal patents prior to Mr. Morgans (who is accredited with the first traffic signal

) so the possibility has to be out there that other "non" mainstream companies existed.
The only markings on the light outside of the reflectors you and Larry point out, is a tag on the inside which says,
E. S. 305 If the light was gutted (no reflectors) and I stumbled on it (not knowing what it was) I would make the assumption
E = Eagle, S = Signal, 3 = 3 section, 0 & 5 = (lens type/hardware/visor configuration
The light is original and I see no sign of it ever being restored. The lenses definitely look original. The lens tabs haven't even started rusting, nor have the reflector retainers, the screws look perfect (tarnished) but look like they haven't been touched since the factory.
The early GE's were all cast visors, this one has sheet aluminum. The reflector hinges are aluminum and the material and method of making them reminds me of what I see in the DT reflectors, meaning they probably were stamped. The door pins I originally thought were brass but turns out they are also aluminum. I can lift them out with my thumb.
I'm not up on my cereal bowl reflectors, but the glass is wavy almost like what you would see if they were hand made / individually made, not smooth like we see in the mass production glass.
We know the 27's date back to the 20's, but when do we see the cereal bowl reflectors being introduced?
I don't know if it's question or just speculation on my part, either way I have more now than when I first posted this thread. So please people, chime in or post your lights if you have them. This is a
PAL research thread.
