Cyldon 13/1


This is an early version of the 13/1. The firebox is a different style from the usual Cyldon type and is steel instead of aluminium. The meths burner is also slightly different. The firebox and burner were soon changed to the styles more typical of later Cyldon models. (See here.)

There is a mystery related to this engine, in that it is very similar to a rare Mersey model of unknown model number. This would suggest that the prototype of the 13/1 was a copy (official or not) of the Mersey engine. If anyone reading this has any definitive information, I would be very interested.

The brass boiler is 1 3/4" diameter x 4 1/2" long. It is fired by a brass cylindrical three wick meths burner. It has a safety valve and a seperate filler plug and overflow plug. The original whistle is missing so I have fitted a reproduction replacement, which is pretty close. It has a dummy chimney. The boiler is held onto the steel firebox with a single brass band.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 oscillating cylinder. The brass cylinder is 5/16" bore x 3/4" stroke. It is a single acting oscillating type. The crank shaft is steel, with a brass disk crank at one end, a small pulley at the other and mazac flywheel in the centre.
