The BSI history for the standard shows "Replaces BS 2484:1954.".

There was a British Standard BS 2484:1961  for concrete cable covers.  Presumably post 1961 covers would be required to have the standard shown on them.

Was there a British Standard prior to 1961?

They are in the ground at the Sally Port, Brompton. No trams anywhere near, but plenty of military stuff nearby.

Hi! Please can you give a location as to where you found it? Looks very much like an old Kent electric power cable slab. Mind you, they could be used anywhere, tram systems for example.
Probably pre nationalization date, say twenties or thirties. Much of the modern network was laid out about that time.

As a purely uneducated guess I would say 1930's, possibly late 20's. The bricks look to be made to interlock as if to cover a conduit, possibly in the ground.

Leofwine,

Is it worth contacting Hanson Brick marketing and see if they can assist with a date. LBC became Hanson became Heidelberg Cement.

So far all I have been able to discover is that London Brick Company 'Phorpres' bricks were made from 1910 until 1974. Phorpres is a play on words as the brick was pressed four times in the manufacturing process. However, I'm not sure if the electricity tiles have the same date range or not.

Annoyingly I know the tiles in my photos must have been put in between 1906 and c.1970, which almost exactly matches the production range of phorpress bricks, so I'm hoping the electricity tiles have a tighter production date range. From other factors it is most likely that these were laid after 1925, but 1925-c.1970 is still a wide date-range.

I have no doubt you have already seen this on the internet, after all I stumbled across a certain flickr image with your name all over it! But for information of others, a link to some history of the LBC....

Anyone know anything about brick history?  I'm trying to find out what the date range is for the production of these London Brick Company Phorpress Electricity Danger tiles. Anyone have any ideas?
