3" Fowler A7 traction engine
 

I have been building this for years and will never get around to finishing it as full size jobs keep interfering! I have all the castings and fittings to finish it right down to the pressure gauge, injector and mechanical lubricator, globe valves etc, A full set of MJ Engineering drawings plus a heap of machined parts ready to fit. All the gearing, diff, winch, crankshaft etc etc is done and assembled. Cylinder mostly done. Have a look on www.capertrading.com under traction engines. The 3" Fowler is a decent size model, practical and driveable.
