A 3 1/2 inch gauge BR Standard Class 4 to the LBSC design.
Silver soldered copper boiler, 80psi working pressure, feed by injector and axle pump with auxiliary hand pump in the tender. Gunmetal cylinders with piston valves actuated by Walschaerts gear, screw reverser in the cab. Mechanical lubricator.
Boiler has had recent hydraulic test and is sound, the engine runs although needs a variety of jobs doing over winter - injector doesn't pick up, pistons or valves blow by.
A handsome design, don't know why more of these aren't made.
