This little gem of an engine was designed and built by Paul Cooper. I don't know if it has a model number. It is made mostly of nickel plated brass. The base is 55.5mm x 50.5mm and fits easily in the palm of my hand.
The boiler is a miniscule 16mm diameter x 42mm length and is fired by a vapourising meths burner.It is fitted with a dummy chimney, a safety valve and a steam regulator valve. There is no water level indication. The steam is fed to the port face of a double acting oscillating cylinder; approx 5mm bore x 9mm stroke. The piston rod connects with a disk crank at one end of the crankshaft, at the other end of which there is a 24mm flywheel and a 7.5mm pulley. It runs very well on compressed air but not atall well on steam. It appears to be priming so badly that most of the water is ejected before it has a chance to run.| Make | Paul Cooper |
