3 1/2 inch gauge LMS "Duchess" - stock code 5862

A 3 1/2 inch gauge LMS "Duchess", running until recently at the owner's club in Scotland - it's obviously been painted but was stripped at some point in its history for a repaint that never happened.

Silver soldered combustion chamber boiler, 80psi working pressure, four safety valves. Feed by injector and axle pump with auxiliary hand pump in the tender. Four cylinders with piston valves actuated by Walschaert's gear to the outside with rockers driving the inside valves.

Build quality is workmanlike rather than show-winning, it really needs some tidying up and painting - that said, the boiler is sound, it ran well enough on air outside the workshop this afternoon (there's a clip of it here).
