This charming miniature overtype is made by Phil Gravett and uses a lot of the same parts as the Jenny Wren. Unusual for a horizontal boiler, the chimney is a flue which passes vertically through the boiler letting hot gases escape through the chimney. The newer Lilliput?s feature a steam dome that is also fitted to the beam engine plant and marine engine although it is non functioning and is used as a filler plug for the water.
