According to page 23 and 24 of "The rise and fall of the Police Box" by John Bunker.
"In 1907 the City of London Police introduced Cast iron Pillars to call the electric Ambulance from Bishopsgate Police Station."
"52 of these pillars were installed in the Square Mile. They were replaced in 1927.
The following photos are of the second style used by the City of London police, I presume these were installed in 1927.
I am not sure if they were installed with the 200 Series telephone as original equipment or if it was a replacement.
The interesting thing about the second style of post is that It has the same crest as the original Ambulance Pillar. But it has the same Fresnel Lantern glass as the Metropolitan Police Post PA2 & PA3 in addition to the 200 series Telephone. It was of similar size as the PA3 Post as well, meaning that it would have made it easy to directly replace.
