Here are some old photos where you see ( badly ! ) some CGE in service. The first picture is about the severe flood in Florence occurred in the 'year 1966, the other is a picture of a town near Florence (about 1955 year ). In the first picture you can see the tip of the spear upon the red light and the old pedestrian signal "ALT/AVANTI" seen behind. In the third picture you can see an inscription in Italian, which concerns the 'ministerial approval of the type of traffic light.
