3 1/2 inch gauge 0-4-0T

A 3 1/2 inch gauge 0-4-0T, of unusual freelance design with marine type boiler incorporating four cross tubes in the firebox, displacement lubricator and slip eccentric valve gear.

Commerically built - possibly as one of a small batch - by "Chelston Model Engineers" who also built stationary boilers and had interests in the designs of various models for which they sold drawings.

Boiler has had a twice working pressure hydraulic test and appears free of distortion or leaks - we would warranty as sound.

Pressure gauge requires replacement, hand pump works, the axle pump leaks copiously from the rubber feed pipe which needs a clip.

Chassis runs on air in either direction in fairly desultory fashion - likely to be better on steam.
