A kit-built "Britannia", put together by an accomplished scratch-builder of other engines (including the super Fowler A7 currently in stock). Like most kit engines, there are "optimisation opportunities", however this one turns over freely and has run around the builder's club track - it hasn't been used recently, anno domini the reason for it's sale.
Silver soldered copper boiler, 90psi working pressure, feed by injector, axle and hand pumps. Cast iron cylinders with piston valves actuated by Walschaert's gear with screw reverser in the cab, mechanical lubricator. Piston valves have been fitted with PTFE rings.
