As the above inventory table suggests that the adjacent illuminated sign was attached to this column, which it clearly wasn't, I suspect that the original column here was probably replaced (and the signlight/plates fitted to their own dedicated post) after 1997.
The opposite signpost had already had its plates transferred to the new post. The Truesigns T8P/54 twin 8 Watt fluorescent signlight was still operational at the time, however.
The next column seemed to be involved in playing a game of "Hide and Seek" - unfortunately, its lack of complete camouflage insured that it was still found relatively easily...
The Beta 2's little brother, the Beta 5, was attached to the next outgoing column.
This was 5 m in height, whereas the preceding columns were all 6 m in height.
Another Beta 5 was installed on a Fabrikat base-hinged column on a gated-off footpath leading to City Road - this installation carried the number of the column whose location was unknown in the above inventory table.
The lantern's bowl clip was missing; hence the (not completely successful) use of insulation tape to secure the bowl to the lantern body.
