Stuart beam engine with Reeves "Monarch" vertical engine - stock code 13180

A Stuart beam engine, mounted on a wooden base along with a Reeves "Monarch" vertical engine.

An older model, the beam engine is nicely made, complete with wood-lagged cylinder and earlier type turned arms for the Watts parallel linkage. It runs well on air, with some wear apparent.

The Monarch is a rarer thing, as I remember we've had one over in the last twenty years! This one turns over, but doesn't currently run air.

Includes free UK shipping.
