A professionally-built "Britannia", completed by John Shawe of Shawe Steam Services in 1992. One of the finest examples I've had in, whilst the paintwork is now starting to get tired, it remains a powerful engine in good mechanical order - motionwork is in excellent condition, the chassis runs on roller bearings and moves at the slightest push. The engine is finely detailed throughout, from cosmetic details like dummy sanding gear and the tender air vents, through to largely hidden bits like the working tender water scoop and finely made "Y"-form exhaust pipe.
Silver soldered coper boiler with combustion chamber, four element superheater. Working pressure 80psi, feed by twin injectors with hand pump in the tender. Gunmetal cylinders with piston valves actuated by Walschaert's gear, screw reverser in cab. Twin mechanical lubricator mounted on running boards.
The engine goes well, running with even beats, the boiler is free-steaming. There's a clip of it running in the workshop here. Cab roof and front of tender are removable for driving.
