E Coppee O
— 23/03/2021Found by Ian Suddaby at the old Heathfield Fireclay Works site. I am not in possession of this example. Possibly have been manufactured by Heathfield Fire Clay Works for the Coppee Coke Co (however a similar firebrick was found at the James Dougall Fire Clay Works at Bonnybridge and therefore Dougall could be the manufacturer?)…
