Stuart triple expansion engine - stock code 11402

A Stuart Triple Expansion engine, one of the most complex designs in their range, complete with Stephensons reversing gear, fed pump and condenser vacuum pump.

Built between January 2005 and May 2006, the engine has been built to a good standard and comes complete with documentation including the Stuart drawings, along with a comprehensive build diary and notes.

Stiff to turn over although without tight spots - we suspect it's never been run.
