Millars-Marshall Tandem Steam Road Roller

It was based on an American patent and then further developed jointly between Marshalls and Millars. There became a need for tandem rollers when asphalt materials developed in the USA became popular in this country. Conventional 3 wheeled steam rollers were too heavy and the rear wheels cut into the road surface.
