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.
