Wall post box

I have photographed this half a dozen times as a "back up blip" and today was such a slow day (just rain and work) that it has finally been blipped. It's outside Isleworth Railway Station, so I don't know if the CCTV people have been wondering why I keep photographing it. As a Queen Elizabeth II box it is not particularly old, but it suffers a bit from being below a ledge where pigeons roost.
