Found by Gloria Conti in the Grahamston, Falkirk area. This example is not in my possession. This brick was likely made by the Greenhill Fireclay Works, Bonnybridge. Believed to be sited at Clayknowes and later taken over and renamed the Greenhill Fireclay Company. . . .
Clayknowes Brickworks, Greenhill, Bonnybridge, Falkirk, Stirlingshire. – They stamped their bricks ‘Claynows’
Greenhill Fireclay Works, Clayknowes, Bonnybridge – Alexander and John Scott owned the farm and brickworks at Clayknowes and Cadgersgate according to the valuation roll of 1865, Slater’s Directory of 1867, refers to the Greenhill Fireclay works being worked by Scott & Walker. The brickworks is not shown on the maps of 1854, so it probably started about 1860. The Greenhill Fireclay Company had passed into the hands of the partners, William Brown and Thomas Brownlee of Glasgow and George Caddell Bruce of Edinburgh by 1875. Brownlee and Bruce still owned it in 1880, but by 1895 when it was owned by James and William Wood, the brickworks was in ruins. The site was used by several explosive manufacturers before and during the First World War and suffered several accidental explosions. No more bricks were made on this site, although a Greenhill Fireclay Company was incorporated in October 1920, with James Ferguson, Managing Director of Lane & Girvan, the Bonnybridge iron founders, one of the principal shareholders. This company was liquidated in 1922, when Ferguson took an interest in the re-structured Glenyards Fireclay Company at Greenhill Railway junction, as a Director of James Anderson & Co. Ltd.
