A particularly well made example of Dick Simmonds' 5 inch gauge "Ajax" design, a good-looking, well-proportioned engine that enjoys a good reputation as a club locomotive.
Commercially-built silver soldered copper boiler by Morewood, 80psi working pressure, feed by twin axle pumps with auxiliary hand pump. Gunmetal cylinders with slide valves actuated by Walschaert's gear with pole reverser in the cab. Twin mechanical lubricators.
A nicely built engine, fit and finish of the motionwork is good, platework is crisply done, the builder has taken trouble to make things like the sliding firehole doors both work well and look elegant. The valve gear and motionwork are crisply machined and in good condition - there are nice touches like generous oil troughs machined in the axleboxes which have kept them in good order. The engine runs well, notching up in either direction - there's a clip of it on the rolling road on a particularly sunny morning recently here.
Complete with a detachable rear panel for the cab and the purpose built stand which you see it on here.
