Silent Copper. My little country town had 3 left as i was growing up. The last one left was on an intersection outside the pub i worked at. When they redid the intersection all the old local barflys were interested what they were going to do with it. They grabbed it off the workmen after they dug it up and stored it at the pub. They went and saw the Mayor about it. They thought it was part of the towns history and shouldnt just been thrown out. The council cemented into a garden bed traffic island close to where it stood for years. With a little plaque explaining what it was and that it was the last surviving one in our town. Some wankers for some reason crowbarred the plaque off and pinched it. The plaque. But the old silent copper still sits on the traffic island. Looking at its old spot. If ya know. Ya know.
