The company was formed by the merger of two famous firms, following the collapse of the AGE group. After World War II the company continued to make motor and steam rollers as well as expanding into other construction equipment. They were still building stem rollers in 1945, with some being produced at the Vickers factory in Newcastle. In 1946 they introduced the G series of Diesel rollers, which had been designed pre war. This was followed by the Aveling Austin 99H Grader, (licensed from an American design). The Shuttle dumper was a popular product as well, with a lot exported to india in 1963.
