Lantern acquired in September 2004.
This lantern is better known as a Revo "Dalek" due to the similarities in appearance of the dimply ends of the bowl resembling the front of the famous Dr Who characters. However, this lantern will not try to exterminate you! The lantern is from Claire Pendrous, and although its previous location is not known, it is believed to have come from the west side of Wolverhampton due to the fact that it hasn't been drilled for a photocell, as many in this area were.
This picture shows how cloudy the bowl now is. The Perspex used is now incredibly fragile, however it is still in a reasonable condition, with only a couple of small holes being present. I am reminded very strongly of the Z9450 in terms of the lantern's appearance. (Trust me to stand in the way of the window while the picture was taken!)
From above, it is easy to see how the lantern would be secured if it was the top entry version (the C13723/T).
Here, the dimples along the bowl can easily be seen. The clouding isn't as bad underneath as less UV light has been able to get to it. This picture shows the dirt that has accumulated in the dimples over time.
As well as the dirt, a swarm of wasps had taken up residence in the lantern. However, they're all dead, and so I don't need to worry about being stung! This completely goes against a sentence in the catalogue: "The lantern is completely weatherproof and will not permit the ingress of dust or insects". When the lantern was new, this probably was a true statement, but over time, the gasket has broken away, leaving only a small piece near the bowl hinges. The enamelled reflector could also do with a clean. This hinges forward, allowing access to the connections. The wires going into the lampholder have been confirmed as being asbestos insulated, and so these will be replaced with modern PVC insulated wires for safety.
I cleaned the bowl and reflector on the 22nd September 2004. Notice that the lamp support has turned slightly - it will actually swivel through 360 degrees as the nuts that hold it in place had become loose over time and had then rusted solid.
This shows how clean the reflector is, as well as the lack of wasps in the canopy! The piece of gasket has been removed, revealing the canopy's original aluminium colour. Notice that the lampholder has had the wires removed now too.
And here they are!
Here is the bowl after a thorough cleaning using fully concentrated Exodus - I've never had to use the full concentrate before but I had to here to remove the dirt from just about every dimple in the bowl, but even so, the dirt wouldn't come off without some heavy elbow grease. Cleaning may have been easier if the bowl could be removed from the hinges, but it is held in place with four screws which have rusted over time. These could obviously be drilled out and replaced but due to the bowl's fragility, I decided not to try this.
This is a close-up of the now clean dimples.
And finally, a picture of the C13723/S working; completely re-wired and now residing alongside my 'control point' for other lanterns. Funnily enough, above the Alpha 8 is the Z9450, one of the C13723/S' main rivals. Both lanterns are very similar in appearance; however, the Z9450 has a deeper, less curved bowl and the reflector hinges sideways, instead of forwards.
