Vintage Liverpool Wardle No 4000 200w SOI lanterns: 2

Showing the top of the concrete column with the steel twin outreach arms.
I've had a look on Google Streetview and the lantern on the right was replaced by a Philips MA50 which was fitted some time before 2008 and was replaced itself with the current LED lantern some time after September 2021.
It appears to have been dayburning since 2015 with a few gaps where is was off!

For a while I have noticed that on Queens Drive road in Liverpool, there have been quite a few of these old low pressure sodium lanterns dotted about and still kicking.
I never did find out what they were but as more and more seem to be being replaced I thought I might as well get out there and grab a few photos while I still could.

*Edit* Turns out these were made by Wardle and are No 4000 series lanterns made in the early 1960's originally for 200w SOI lamps!

Queens drive is a history lesson of streetlighting in itself, there is a right mix and match of lanterns as there has been various piecemeal replacements over the decades.
You have these lanterns, then you have "modern" SOX replacements like G.E.C Z9555's and then later Philips MA50's. There are also an absolute cornucopia of SON lanterns and then finally, their contemporary LED replacements.
