5 inch gauge part-built Hunslet

A curious thing, we're not quite sure of the provenance of this one. Allegedly a commercially produced 5 inch gauge Hunslet - certainly the chassis components look professionally made, possibly designed for batch production and BZP finished. Boiler and saddle tank may or may not have originated with the engine - they look of a different vintage, boiler is robustly constructed, if not exactly a thing of beauty.
