Silver-soldered copper boiler of combustion chamber design with superheater. Boiler feed by twin injectors and auxiliary hand pump in tender. Three cylinder with piston valves actuated by Gresley-Holcroft valve gear. Motion work, all locomotive plate work and ash pan are in stainless steel. Semi-scale backhead with twin water gauges (with blowdowns piped below the footplate), pressure gauge, steam chest pressure gauge, screw-reverser, blower, whistle and steam brake control.
Eight wheel tender with disc wheels, screw-down brake, water feeds for injector and hand pump in rear. The tank is in stainless steel with water filters fitted.
The paintwork is worn in places - in particular the wheels and parts of the smokebox. It is entirely presentable as-is, but could be re-finished to produce an exhibition-quality engine. The sliding part of the cab roof is missing.
The engine runs very well with negligible wear in any of the moving parts. It will pull away just off mid-gear with less than 30 psi on the gauge. At the working pressure of 100 psi a delicate hand is required on the regulator - think starting 500 tons out of Kings Cross!
