Little is known about this model other than it's make, model number and approximate date. It is a simple overtype, solidly built.
The boiler is 4" long x 1 3/4" diameter and is fired by a meths burner. It is currently fitted with an SEL burner, which is similar in style to the original. The boiler has a safety valve and a small steam dome. There is no water level indication.
Steam is fed directly to the back of the oscillating cylinder port face. The cylinder is 5/16" bore x 1/2" stroke. It is a single acting oscillating cylinder. The piston and con rod are cast in one piece, with a barrel shape to the rod. The crank shaft has a small disk crank at one end and a 1 3/4" diameter cast mazac flywheel at the other. Exhaust is fed to a base mounted chimney.
General condition is good and the paintwork appears to be original. There has been some resoldering done on the boiler.
