Stuart No.9 mill engine - stock code 12821

A Stuart No.9 mill engine, complete with boiler feed pump, governor and displacement lubricator.

Built to a good standard, we like the faux girder platform it sits on (although the base could have used a second coat of paint).

The engine turns over freely and runs on air, with opportunity for improvement by resetting the valve. The crank tracks slightly from side to side when running, which could be taken up by repositioning the smaller flywheel on its shaft.

Includes free UK shipping.
