Thorn Beta 79

Here is a Thorn Beta 79 on an unpainted Fabrikat column. These would have been common on side streets in Newham starting from the early 90s, so I’m unsure how this one managed to survive for so long! I believe this is the rare 100w version too, as I took a closer look and the lampholder appears to be located at the front of the lantern, which is typical for 100w Beta 79s.
