69CG. Dawley Trading Estate, Stalling's Lane, Kingswinford, Dudley, West Midlands With thanks to Dwight for informing me of these Survivors. Installed throughout the Trading Estate are a number of 25 ft (8 m) Stanton 8 concrete columns with F-type side-entry brackets, and supporting (mostly) AEI Amber Mk IV 51/74007 lanterns from the late 1950s or early 1960s. The lanterns were designed to run 140 Watt SO/H / SOI/H lamps; the precursor to the later 90 Watt SOX (low pressure sodium) lamp. Sadly, the lights all appear to have become disused, with some suffering heavy vandalism.

The first installation to be spotted was one such damaged example.

The fragile Perspex bowl has been smashed to pieces, with the front section bearing the brunt of the attacks.

From the other side, more of the bowl is intact.

Many of the brackets are showing signs of spalling around their joints with the columns.

Remarkably, the lamp still seems to be intact, despite its broken surroundings.

Judging by the design of the lamp, it appears to be a GEC / OSRAM 'SuperSOX' type, possibly dating back to the early 1980s.

The next lantern was in much better condition.

Aside from the insecure bowl clip, and a carpet of dirt on the underside of the bowl, the lantern is in good condition for its age.

Two of the columns on the estate had been fitted with GEC Z9454s; this is the first.

This bracket also had damage at its connection to the lantern.

The entire bowl was missing here, as was the lamp support spring, and every part of the lamp, save for the bayonet cap.

With the lamp control gear being mounted remotely, but the lantern having a NEMA photocell socket, multiple wires are connected.

I thought that a stamped date code might still survive at the front of the lantern, near the identification label. None appeared to remain, however.

Another column supporting an Amber followed; this column looked to have been struck by a vehicle, as it was leaning backwards slightly.

The front hinge had broken away; possibly, as a result of the collision.

Another leaning column followed; this too supported a Z9454.

Remarkably, although the bowl was also missing once again, the lamp was intact (albeit, broken internally).

The column's inspection door was missing, allowing the internal wiring to be viewed. Notice that any outgoing wiring from the Lucy cut-out has been removed.

Removing the heavily-discoloured Sangamo S250 time switch front cover revealed that its dial was frozen at around 12:15 in mid-January. This particular dial includes additional switching points to allow for the lantern to be turned off at 1 AM (2 AM BST) and back on at 5 AM (6 AM BST), when required.

A fantastic AEI leak transformer would have operated the lamp when the lantern was in use. Notice that the old VIR (Vulcanised India Rubber) cabling to the lantern has perished, exposing the tinned copper inner cores.

Another view of the same installation, from the side.

Once again, the bracket has spalled at the same position that is seen on the others.

Not only has the lamp's outer bulb lost vacuum; the arc tube has also ruptured, causing the sodium within it to oxidise; hence, the white appearance of the tube.

The final column saw a return to supporting an Amber.

Thankfully, this example was undamaged.

Only a small amount of dirt existed in the bowl.
