A 5 inch gauge LSWR Adams 4-4-0, from the builder responsible for the GWR Mogul sold recently. An older engine, it steams very freely and runs well but needs an overhaul and repaint - it was reboilered in 2005.

Silver-soldered copper boiler by Western Steam, working pressure 80psi, feed by twin injectors with hand pump in tender. Mechanical lubricator. Stephenson's valve gear with screw reverser in cab.

There's a clip of it running in the workshop recently here.
