BAP

Found in woods once owned by the Bonnybridge Silica & Fireclay Co Ltd near Drum Farm, Bonnybridge.

Unidentified maker but the find location would suggest Scottish origins but … (Note – SBH – Bonnybridge Silica & Fireclay Co Ltd and Bonnyside Fireclay Works and Roughcastle Fireclay Works, all of Bonnybridge, all appear to have manufactured fire bricks for the South American railways).

BAP – Probably made for the South American railway network as per this link – Click me.

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.
