From the same builder as the GWR 14xx tank currently in stock, this engine has been put together from a kit and steamed only once since.
Silver-soldered copper boiler, working pressure 80psi, feed by axle pump and injector with auxiliary hand pump on the footplate. Twin safety valves. Cast iron cylinders with slide valves actuated by Stephenson's valve gear with pole reverser in cab. Mechanical lubricator.
The engine is fully assembled and nicely finished but requires further fettling - it is still fairly stiff to turn over, which is going to be a tall order for the diminutive cylinders to overcome and still produce anything useful at the drawbar.
Complete with a set of the original assembly instructions.
