Looks like a normal Durasig
Note the poor quality/mixing of the plastic. The fading should be even colors. Since it's swirled like that either it wasn't mixed well or the flow into the mold was poor.
Standard poly lense, these in good shape considering the rest of the signal.
Doors are held on with split pins, bent, instead of the later "allen key" shaped pieces. These are a lot easier to pull out and such. I wonder how many came loose in service.
This fella got quite the sunburn. He must have been hanging in the shadow of someone else.
The wingbolts are quite...unusual. Appear to be studs, cut down in the center so they become captive screws, and then the wing nut is attached and welded in place.
The bosses that the brass nuts press into are lousy. Each signal had at least one brass nut broken away and attached to the wingbolt on the door.
The Gasket-Lens-Reflector assembly. Not a bad idea, considering. I like the added touch of a reflector on the socket insert.
