Found at South Queensferry.
Hepworth Ceramic Holdings plc (GR-Stein Refractories Ltd. parent co) bought the Bonnybridge Silica & Fireclay Co. Ltd in 1972, closed Bonnybridge works in 1973 and closed Chapelhall in 1980. Therefore between 1972 and 1980, GR-Stein Refractories probably continued to manufacture bricks with this trademark for a time.
I suspect this special was used to line a boiler or similar.
At each end there is a semi circular design which when butted together with the next brick would form a bolt fixing which would pull the brick tight to the boiler wall.

Found by Claudio Ernesto Rios. Claudio states – The bricks were found in the City of Zárate, Buenos Aires, Argentina. In a fridge (almost totally destroyed today) the fridge’s name was Smithfield Refrigerator of English capital, built in 1903, so I would believe those bricks were manufactured in the last decade of the 19th century….
