yop, those are the old Gentrols. Fortran used to make them, we've got all the prints somewhere on the system still. There are still some lenses kicking around as they were all masked in house. We actually used to mask everything in house, PEDs arrows, transit etc....
Not sure who does it now though. The old 12" GE/Fortran signals were used initially with either a round or square door as per the colour.
No idea who is making those LEDs. I'd guess Tassimco, but I could be wrong.
