One of the largest factory complexes in Grantham, once the headquarters and principal factory for the production of road rollers (with the legendary brass horse rampant), dump trucks, motor graders and other earth moving equipment. Aveling Barford Ltd was yet another firm invited to come to Grantham in the mid 1930s. It was formed by the amalgamation of the roller activities of Aveling and Porter of Rochester, Barford and Perkins of Peterborough and Ruston and Hornsby of Lincoln. The latter company provided its new home from its previous boiler making shop and First World War 'shadow factory' building which was used to make submarine engines. {1}
