Ben WW, good evening.
I recall some time ago now watching a TV Programme with I think Fred Dibna knocking down a Chimney somewhere?
There was a single Black brick built into the large tall chimney.
It was expounded in the TV show that the Black Brick was incorporated as a mark of respect to someone who had died in an industrial accident whilst constructing the chimney.
The Chimney being blown down was well over 100 Years old [at that time] that TV show was many years ago now?
It would appear fitting to have some sort of Commemoration for whatever reason? The practice it appears has been on going for some considerable time?
Ken.
