The 13/3 is similar to the 13/1 but with mostly minor differences.
The main difference being that it has a metal base instead of wood.
Both are simple oscillating cylinder models - very conventional in style.
Typical of Cyldon, all major parts are made from non-ferrous materials - brass, aluminium, copper and mazak; the only exceptions being small parts like screws, springs etc.
The only painted part is the mazak flywheel.

The brass boiler is fired by a brass cylindrical three wick meths burner.
It has a safety valve and a separate filler plug and overflow plug and a dummy chimney.
Unlike the 13/1, it has no whistle.
This is strange as all the other Cyldon models do have whistles.
The copper steam pipe exits from the bottom of the boiler inside the firebox, thus getting a very small degree of superheat.

The steam is fed directly to the back of the port face of the brass single acting oscillating cylinder.
The crank shaft is one of the few steel parts, with a brass disk crank at one end, a small pulley at the other and mazak flywheel in the centre.
The simple brass engine bracket is fixed to the aluminium base plate; which has a rubber foot at each corner.
