Weeden 903

c 1940's

This is one of Weeden's simpler engines. It is a single cylinder, single acting, oscillating cylinder engine. However, the cylinder itself and it's mounting bracket appear to be designed for double acting use, complete with all the necessary ports. This is probably an example of parts standardisation as I've been informed that the engine always was only single acting. The Boiler is 2 1/4" diameter x 5 1/8" long with a safety valve, whistle and steam dome. The whistle is missing it's top half and the dome should have a chimney attached (presumably purely cosmetic as not even the steam exhaust goes through it). It is heated electrically, using 110V The steam feed pipe has been replaced at some time. It is copper whereas the original was brass. Also, the boiler fittings are bent over slightly, as if the engine has been dropped at some time in the past. The cylinder is approximately 8mm diameter x 16mm stroke. The flywheel is 2 5/8" diameter and appears to be lead. The paintwork appears to be original and there is negligible rust on the few steel parts.
