Well here at Lancaster Gate W2 within the City of Westminster we find another bollard but this time instead of the crest of the council we have a urban clearway sign on a information plate...
When you enter Hyde Park via Lancaster Gate you'll notice this rather plain looking bollard with signs attached informing those wonderful people who cycle to effectively dismount..... 
This must be one of the most dandy and ornate bollards you will find anywhere in the capital.....
Yes here is a City of Westminster Bollard very solid and notice the two third ribbed design with integral coat of arms approximately half way up.
Well here is a Thames water bollard, in fact a bollard with a real use other than telling you to keep left or seeking to protect a public building.......
