That particular brick has made its way to Northumberland from The Withnell Brick and Terra Cotta Company Ltd at Abbey Village, Withnell, Chorley, Lancs probably some time in the early 2oth Century.
So from 1912 the Internet Archive site here https://archive.org/details/CatalogueNo ... ?q=plastic
has Catalogue No4 of the Withnell Brick and Terracotta Company (1912) Ltd
Contributed by the Canadian Centre for Architecture.
How on earth has that catalogue survived and what's more from its slumbers, presumably within the Canadian Centre For Architecture, it has been scanned into the Internet Archive to be found April 18th 2023 on the back of a photographed brick, and made it to the FCF Trivia Investigation Thread. Not many will have a flick through but ever wondered where the rich variety of terracotta special tiles in our buildings came from, this particular brickworks made a lot more than bricks
