The engine in the steam mill at Upminster was manufactured by Matthew Boulton and James Watt at their Soho works in Birmingham. It was a modified Bell Crank engine rated at 6 hp and had a 10ft diameter flywheel. It drove two pairs of millstones and the drive shaft was extended into the windmill to run auxiliary machinery.
