Stuart 10H with gas-fired boiler

A steam plant comprising a gas-fired vertical copper boiler fed by a hand pump with water tank, coupled to a nicely made Stuart 10H engine fitted with displacement lubricator. The boiler is fitted with pressure and water gauges, the gas burner allows it to be throttled back such that it produces just enough steam for the engine to tick over, rather than spending the whole time roaring away on the safety valve.

The whole plot is rather nicely put together, the engine runs very smoothly.

Base 14 x 12 inches
Boiler 4 inch diameter
Pump 1/2 inch diameter ram
