Greenly vertical engine with reversing gear

A superbly built vertical launch engine, using Henry Greenly's well-know design doubled up. The pictures speak for themselves really, fit and finish of everything is excellent, the engine runs very well. There is minor tarnishing on the top cylinder cover and some cosmetic marking of the cylinder cladding sheet, it is otherwise in ex-workshop condition.

Complete with a set of drawings and a part-built mechanical lubricator.

There's a clip of it running on compressed air in the workshop here.
