2 inch scale Allchin agricultural engine

A 2 inch scale Allchin agricultural engine, complete and running on air, although requiring further work.

On test there were leaks noted from the bottom gauge fitting, safety valves, glands and regulator. The water gauge really needs replacing, it is made of brass, not a suitable material for any fitting screwed directly into the boiler.

The engine runs on air in either direction, with slack clearances and/or wear apparent in the crosshead, crank bearings and eccentrics - whilst making up bushes, the rear wheels could use a pair too.
