An 3 1/2 inch gauge "Rob Roy" 0-6-0T to the Martin Evans design, complete with drawings and carrying box. Complete and turns over freely, it looks to have been unused in a long time although stored well, all bright parts oiled.
Silver soldered copper boiler, 80psi working pressure, two element flue tube superheaters, feed by axle pump and injector with auxiliary hand pump in tank. Boiler looks nicely made with nicely flanged plates and good solder penetration. Gunmetal cylinders with slide valves actuated by Stephenson's gear, pole reverser in the cab. Mechanical lubricator.
Regulator leaks copiously, however after an oil round, the engine ran very well in both directions on air (there was literally no stopping it...)
