A well-made 7 inch gauge Kerr Stuart "Wren", built to Ken Swan's excellent design. I've had several of these (including which lived on our railway up at home for a while) - they go well.
Silver-soldered copper boiler, working pressure 80psi, feed by injector and crosshead pump, lever ball-valve blowdown beneath footplate. Cast iron cylinders with slide valves actuated by Hackworth gear, pole reverser in cab, mechanical lubricator.
The motionwork is in particularly good order, with negligible wear I was impressed when I drove this engine at Evergreens Miniature Railway last summer on one of my numerous "circuit-bashing" days out with "Stafford", clocking up test miles on the prototype engine. The Wren ran quietly, its well-designed tender making for a comfortable driving position.
