All the heads I saw were the modern poly PEEK's. (I can also verify that none of the 3+ antique stores in town had any signals.) Not sure about the cameras, this was waaay outside of London and there's no real intersection to speak of, just a very busy main street and a quiet pedestrian crossing.
There was a nice assortment of Ped equipment however. This intersection had lighted pushbuttons, when pushed the white bar turned on saying WAIT. There was a normal European man 8" red-green head for crossing. I didn't find it handsome but at least I found it handy.
Illuminated WAIT, bad photo.
This other intersection was a real treat. Tight confines meant there's no place for ped signals (the lorries would take them off the first time they passes) so they use secondary pushbutton signs in place of the signals. Quite a change compared to back at home, where we'd either have to watch the vehicle heads, or just have no signal at all.
