Large freelance mill engine - stock code 13069

A large scratch-built horizontal engine of freelance design - what it lacks in aesthetic refinement it makes up for by running very nicely down to 5psi on air.

Lots going on when the thing is running, with mechanical lubricator and water pump - which both work - and Watt governor, which doesn't.

Includes free UK shipping.
