|4 1/2 inch scale Burrell 6nhp agricultural engine - stock code 7466|
An older 4 1/2 inch scale Burrell 6nhp agricultural engine, built to the Plastow design. A well-built engine, paintwork is getting tired and it requires some minor work including lapping in a leaky regulator (a problem pretty much endemic in this design) and fettling the safety valves which accumulate. Boiler is sound, it's recently had a twice working pressure hydraulic test and ultrasonic thickness survey.
Steel boiler with expanded tubes, 110psi working pressure, twin Ramsbottom safety valves. Cast iron cylinder with slide valve actuated by Stephenson's gear. Mechanical lubricator. Two speed transmission with differential, rubber tyres, winch behind nearside rear wheel.
Complete with a driving seat which fits onto the tender, with jockey wheel beneath providing support for the larger driver...
