A 7 1/4 inch gauge "Terrier", built to a good standard and complete with driver's truck.
Silver-soldered copper boiler, feed by twin injectors fed by water from the driving truck tank. Cast iron cylinders with slide valves actuated by Stephenson's gear with pole reverser in the cab. Mechanical lubricator. Vacuum ejector fitted piped through to the braked driving truck - gauge and driver's brake valve in the cab, there is a vacuum-limiting valve and reservoir in the truck.
Built by an experienced model engineer, the engine runs particularly well, there's a clip of it on the bench in the workshop last week here.
Complete with a set of drawings.
