Between the cap and collar there is the arms of the City of London. Below the collar many have the details of the Act under which the posts were erected. On the base of the marker are the details of the casting company - Henry Grissell, Regents Canal Ironworks, London.

These inscriptions are usually dated. The columns erected under the 1851 Act have the inscription recording the 1861 Act screwed over the original (in some cases the plates have been lost). There are other minor variations.

The body in the post, including the cap, is white. The coat of arms depicted is that of the City of London, with the shield bearing the Cross of St. George and the Sword of St. Paul, painted red on a white background.

Beneath the coat of arms is to be found the letters "24 & 25 VICT. CAP 42". This refers to the Act of Parliament which led to the setting up of the posts and signifies the 24th and 25th year of the reign of Queen Victoria (1861) and the 42nd chapter of that act.
